This study seeks to explain the origin of the fast of the 13th of Adar. The practice of fasting on this day is puzzling for a number of reasons. Although the Bible describes fasting in the year of the Purim threat, this fast occurred in Nissan and the weeks thereafter. Nor does tannaitic or amoraic literature mention the practice of fasting on the 13th of Adar. To add to the puzzle, Megillat ta‘anit, compiled in the first century ce, includes the 13th of Adar as a day on which Jews were prohibited from fasting.
It is true that the practice of fasting on the 13th of Adar is referred to in the She'iltot of R. Aḥai Gaon, an early geonic work. But recent scholarship suggests that the relevant she'ilta (discourse) made its way into this work some one or two centuries after the work left the hands of R. Aḥai in the eighth century.Footnote 1 The earliest reference to fasting on the 13th of Adar occurs, instead, in a geonic responsum included in Midrash Tanḥuma. This responsum has not been closely analyzed until now. It is there that we find the clues to the origin of this fast.
I. Fasting in the Year of the Purim Threat
The book of Esther records that the decree to destroy the Jews was issued on the 13th of Nissan (Esther 3:12). It then mentions fasting in two contexts. In verse 4:3, it is told that Jews expressed great mourning wherever they received news of the decree, reacting with fasting, crying, and wailing. Since it would have taken weeks for the decree to be spread throughout the Persian Empire, the implication is that fasting in the Jewish communities started in the middle of Nissan and was ongoing for weeks. In verses 4:16–17, we are told that Esther requested that Mordecai instruct the Jews of Shushan to fast for three consecutive days,Footnote 2 and that Mordecai complied with her request.
Much later, at 9:30–31, we learn that letters were sent to Jews in all the provinces, instructing them to keep the holiday of Purim in future years, as Mordecai and Esther had commanded them, “and as they had accepted upon themselves and zar‘am the matters of the fasts and their outcry.”Footnote 3 If zar‘am here takes on its usual meaning of “descendants,” this phrase could suggest that Jews of all the provinces had already taken upon themselves and their descendants the duty to commemorate the fasts described at 4:3, or the three consecutive days of fasting observed by Esther and the Jews of Shushan.Footnote 4 The phrase could alternatively refer to the Jews’ practice of fasting in connection with remembering the destruction of the First Temple.Footnote 5
The most likely interpretation, however, is that here zar‘am means “children,”Footnote 6 and that the phrase refers to the fasts observed in the year of the threat. The reference could be to the fasts observed by the Jews throughout the provinces, or to the three days of fasting observed by the Jews of Shushan, or to both.Footnote 7 The significance of the instruction at 9:30–31 is that just as the Jews and their children were ready to fast in the days of their distress, so should they be willing to rejoice on the anniversary of their deliverance. No verses in Megillat Esther refer to fasting on the 13th of Adar.Footnote 8
II. The 13th of Adar in I and II Maccabees and Megillat Ta‘anit
Both I Maccabees and II Maccabees record details about the defeat of the Syrian military commander Nicanor by Judah and his men, in a battle fought on the 13th of Adar. This battle took place in 161 bce, a few years after the rededication of the Temple in 164. I Maccabees records:
[T]he victors cut off the head of Nicanor and his right hand, which he had so presumptuously raised in oath, and brought and raised them where they could be viewed in Jerusalem. The people were overjoyed and observed the day as a day of great rejoicing. They decreed that the day, the thirteenth of Adar, should be observed annually.Footnote 9
And the following is the relevant text in II Maccabees:
[Judah] had the severed head of Nicanor hung from the Akra …. By a unanimous vote of the people they decreed that they would by no means let that day pass unmarked, but that they would keep as a special day the thirteenth of the twelfth month, called Adar in Aramaic, the day before the Day of Mordechai.Footnote 10
Josephus, too, notes that this day was observed as a holiday in his own time:
Now the victory took place on the thirteenth of the month which is called Adar by the Jews …. And the Jews celebrate their victory every year in this month, and observe this day as a festival.Footnote 11
Although these sources record the 13th of Adar as a festive day, they do not record a prohibition of fasting on this day.Footnote 12 To find that prohibition, we have to look to Megillat ta‘anit,Footnote 13 a list of approximately thirty-six Jewish holidays, mostly from Hasmonean and Roman times. Fasting was prohibited on these holidays; on the more important ones, eulogizing was forbidden as well. Megillat ta‘anit includes the 13th of Adar as one of the days on which eulogizing was prohibited.Footnote 14 The day is referred to as Yom Nikanor,Footnote 15 an obvious reference to the event above.
In ascertaining when the fast on the 13th could have arisen, we need to consider when the holiday of Yom Nikanor ceased being observed in Babylonia. Babylonia is of interest to us because (as will be shown) it is the place where the fast of the 13th was first observed. The last clear evidence of any of the Jews of Babylonia observing any of the holidays mentioned in Megillat ta‘anit comes from a story about R. Naḥman (late third–early fourth century).Footnote 16 Nonetheless, some have argued that the holidays may have been observed in Babylonia for several centuries after his time.Footnote 17
III. Babylonian Geonic Sources That Refer Briefly to the Practice of Fasting on the 13th of Adar
Several Babylonian geonic sources make brief reference to the practice of fasting on the 13th of Adar. The sources in this section date from the ninth century ce and later. The earliest such source is a responsum of R. Natronai,Footnote 18 head of the academy at Sura from 857 to 865 ce.Footnote 19 R. Natronai writes that on the fast days after the Shabbat shel regel,Footnote 20 and on all fast days,Footnote 21 whether on fixed dates or decreed by beit din, and בתענית פורים,Footnote 22 the practice was to read va-yeḥal Moshe at both shaḥarit and minḥah.Footnote 23
Another source is the Siddur of R. Se‘adyah (882–942),Footnote 24 which provides texts of three seliḥot for the 13th of Adar in the same section as that of seliḥot for the 9th of Av, the 17th of Tammuz, the 3rd of Tishrei, and the 10th of Tevet.Footnote 25 Writing in Arabic, R. Se‘adyah calls the fast צום אלמגלה (the fast of the Megillah).Footnote 26
The fast is also referred to in a responsum that constitutes a reply from R. Sherira (d. 1006) and R. Hai (d. 1038) to R. Jacob of Kairouan.Footnote 27 We do not have the actual responsum, but we do have an index to a collection of geonic responsa in which its compiler recorded the first few words of each responsum and the name of the relevant talmudic tractate. For this particular responsum, the compiler wrote the following in his index: יג באדר רגילין אנו לנפול Footnote 28יוש ובתענית (on the fast of the 13th of Adar, it is our practice to recite the Taḥanun prayer), and the name of the tractate, Ta‘anit.
Also, a responsum addressed to R. Hai inquires whether, in the case of a hakhnasat kallah that occurs on a fast day such as the 13th of Adar, the one who makes the blessing on the cup of berakhah is permitted to drink.Footnote 29
An anonymous geonic responsum includes the following statement: השני של אדר הראשון נמי מתענין כי”ג של אדר וי”ג (on the 13th of the first Adar [in a leap year], we also fast as on the 13th of the second Adar).Footnote 30
Finally, Sefer ha-mikẓo‘ot, a work by an unknown author from the late geonic period, refers briefly to the fast, as will be discussed in Part VI.Footnote 31
IV. Midrash Tanḥuma and the She'iltot of R. Aḥai Gaon
An anonymous Babylonian geonic responsum that made its way into Midrash Tanḥuma refers to a practice of fasting on the 13th of Adar.Footnote 32 A discussion similar to that found in this responsum also occurs in the She'iltot of R. Aḥai Gaon,Footnote 33 a work composed in eighth-century Babylonia.Footnote 34 Recent scholarship, however, strongly suggests that the relevant she'ilta is a later addition that made its way into the work one or two centuries after the text left the hands of R. Aḥai.Footnote 35
Both the geonic responsum and the relevant she'ilta record an interpretation of certain verses in Chapter 9 of the book of Esther and of the statement of the Amora R. Samuel b. Isaac: י״ג זמן קהילה לכל היא (the 13th was a day of gathering for all).Footnote 36 This interpretation asserts that the statements in the book of Esther at 9:1–2 and/or 9:16–17 that the Jews gathered themselves (נקהלו) on the 13th of Adar, and the above statement by R. Samuel b. Isaac, all indicate that the Jews fasted on the 13th of Adar in the year of the threat.Footnote 37 Also, both the geonic responsum and the relevant she'ilta interpret the term yom ha-kenisah in M. Megillah 1:1–2 as a reference to the 13th of Adar as a fast day (the day on which the Jews gather to fast).
M. Megillah 1:1–2 reads as follows:
מגילה נקראת באחד עשר בשנים עשר בשלשה עשר בארבעה עשר בחמשה עשר לא פחות ולא יותר. כרכין המוקפין חומה מימות יהושע בן נון קורין בחמשה עשר. כפרים ועיירות גדולות קורין בארבעה עשר אלא שהכפרים מקדימין ליום הכניסה:
כיצד חל להיות יום ארבעה עשר בשני כפרים ועיירות גדולות קורין בו ביום ומוקפות חומה למחר. חל להיות בשלישי או ברביעי כפרים מקדימין ליום הכניסה ועיירות גדולות קורין בו ביום ומוקפות חומה למחר. חל להיות בחמישי כפרים ועיירות גדולות קורין בו ביום ומוקפות חומה למחר. חל להיות ערב שבת כפרים מקדימין ליום הכניסה ועיירות גדולות ומוקפות חומה קורין בו ביום. חל להיות בשבת כפרים ועיירות גדולות מקדימין וקורין ליום הכניסה ומוקפות חומה למחר. חל להיות אחר השבת כפרים מקדימין ליום הכניסה ועיירות גדולות קורין בו ביום ומוקפות חומה למחר:
The Megillah may be read on the 11th, 12th, 13th, 14th, and 15th, but not earlier or later. Towns that were surrounded by walls at the time of Joshua son of Nun read on the 15th. Villages and cities read on the 14th, but villages may advance their reading to yom ha-kenisah.
How does this occur? If the 14th falls on a Monday, villages and cities read that day, and walled towns read the next day. If it falls on a Tuesday or Wednesday, villages may advance their reading to yom ha-kenisah. Cities read that day (the 14th), and walled towns read the next day. If it falls on a Thursday, villages and cities read that day, and walled towns read the next day. If it falls on Erev Shabbat, villages may advance their reading to yom ha-kenisah. Cities and walled towns read that day (the 14th). If it falls on Shabbat, villages and cities may advance their reading to yom ha-kenisah. Walled towns read the next day. If it falls on the day after Shabbat, villages may advance their reading to yom ha-kenisah. Cities read that day (the 14th), and walled towns read the next day.Footnote 38
These sections of the Mishnah permit villagers to fulfill their Megillah obligation on the 11th, 12th, or 13th of Adar under certain conditions. In the plain sense of these sections, yom ha-kenisah refers to Mondays and Thursdays,Footnote 39 and the teaching is that the reading for the villagers may be advanced to these days, when the villagers enter, or gather in, the cities.Footnote 40
But in the interpretation adopted by the geonic responsum and the relevant she'ilta, yom ha-kenisah means the fast of the 13th of Adar (the day on which the Jews gather to fast). The reading for the villagers is allowed to advance because the date of the observance of the fast day is advanced due to a prohibition of fasting on Shabbat and Erev Shabbat that is read into the Mishnah. In this interpretation, the advanced fast day is a day upon which the reading for the villagers is allowed.Footnote 41 If the 14th fell on a Sunday, the fast would be observed on Thursday, the 11th.Footnote 42 If the 14th fell on Shabbat, the fast would be observed on Thursday, the 12th. If the 14th fell on Erev Shabbat, the fast would be observed on Thursday, the 13th.Footnote 43
The following is the relevant passage in Midrash Tanḥuma:
ותשובת שאלה זו ממתיבתא שאלו הא דתנן מגילה נקראת באחד עשר בשנים עשר בשלשה עשר בארבעה עשר בחמשה עשר לא פחות ולא יותר, וא״ר יהודה אימתי בזמן שהשנים כתקנן וישראל שרוין על אדמתן, אבל בזמן הזה הואיל ומסתמא בקיאין הן אין קורין אותה אלא בזמנה והלכה כת״ק או הלכה כרבי יהודה, השיבו בין לרבי יהודה בין לת״ק מגילה אינה נקראת אלא בזמנה הכי קאמר ת״ק כרכין המוקפין חומה מימות יהושע בן נון קורין אותה בחמשה עשר כפרים ועירות גדולות קורין בי״ד אלא שהכפרים מקדימין ליום הכניסה והא דתנן מגלה נקראת בי״א בי״ב בי״ג וכו׳ ליושב בתענית שכבר פי בסוף המשנה אלא שהכפרים מקדימין ליום הכניסה, ומאי יום הכניסה יום הקהל,׳ דאמר מר שלשה עשר יוםFootnote 44 קהלה לכל היא דכתיב ובשנים עשר חדש הוא חדש אדר בשלשה עשר יום בו וגו׳ נקהלו היהודים בעריהם וגו׳ נקהלו וגזרו תענית בשלשה עשר באדר אבל ארבעה עשר יו״ט הוא דכתיב ונוח בארבעה עשר בו ועשה אותו יום משתה ושמחה, ובשושן הבירה לא נחו אלא בחמשה עשר לפיכך שושן וכל המוקפין קורין בט”ו ועושין יום טוב. זה ששנינו מגילה נקראת וכו,׳ ליושב בתענית שאסור לישב בתענית בשבת שאם חל י״ד להיות באחד בשבת אסור להתענות בשבת ובערב שבת נמי אסור מפני טורח שבת אלא מקדימין ומתענין בחמישי שהוא אחד עשר באדר. ואם חל ארבעה עשר בשבת אסור להתענות בע״ש מפני טורח שבת שעיקר תענית סליחות ורחמים הוא,Footnote 45 ואתי לאימנועי מכבוד שבת, וכבוד שבת עדיף מאלף תעניותFootnote 46, דכבוד שבת דאורייתא ותענית דרבנן ואתי כבוד שבת דאורייתא ודחי תענית דרבנן, אלא מקדימין ומתענין בחמישי בשבת שהוא י״ב, ואם חל י״ד בע״ש מתענין בחמישי שהוא שלשה עשר וכן פי׳ במשנהFootnote 47 כיצד חל להיות בשני כפרים ועירות גדולות קורין בו ביום ומוקפין חומה למחר, חל להיות בשבת או באחד בשבת כפרים מקדימים ליום הכניסה וכו,׳ אבל ט׳ באב שחל להיות בשבת מאחרין לאחר שבת מפנ׳ שהוא פורעניות לכך מאחרין ולא מקדימיןFootnote 48 .ומהני שמעתתא ילפינן דלא יתבינן בתענית בע”ש בעינוי הרשות לא צבור ולא יחיד כלל וכן הלכתא.
The answer to this question comes from the Academy:
They asked: It was taught that the Megillah may be read on the 11th, 12th, 13th, 14th and 15th, but not earlier or later. R. Judah said that this rule is only in effect when the calendar is established by the testimony of witnesses and Israel dwells on its own land, but in our timesFootnote 49 … the Megillah can only be read on the proper date (the 14th or 15th). Does the halakha follow the first opinion or does it follow R. Judah?
They responded: According to both R. Judah and the first opinion, the Megillah can only be read on the proper date. The following is what the first opinion meant. Towns that were surrounded by walls at the time of Joshua son of Nun read on the 15th. Villages and cities read on the 14th, but villages may advance their reading to yom ha-kenisah. When the Mishnah taught that the Megillah may be read on the 11th, 12th, 13th, etc., that applied to one who is engaged in fasting, as it was taught at the end of the Mishnah: “but villages may advance their reading to yom ha-kenisah.” What is yom ha-kenisah? The day of gathering, as it is stated (in the Talmud): The thirteenth was a day of gathering for all, as it is written (Esther 9:1–2): “In the 12th month, the month of Adar, on its thirteenth day … the Jews gathered themselves in their cities.” They gathered themselves and decreed a fast on the 13th of Adar. But the 14th was a holiday, as it is written (Esther 9:17) “and they rested on its 14th and made it a day of feasting and gladness.” In Shushan ha-birah, they only rested on the 15th. Therefore, Shushan and all walled towns read on the 15th and make that a festive day. When the Mishnah taught that “the Megillah may be read (on the 11th, 12th, 13th … )” that concerned one who is engaged in fasting, because it is forbidden to engage in fasting on Shabbat. If the 14th falls on the first day of the week, it is forbidden to fast on Shabbat. It is also forbidden to fast on Erev Shabbat, because of the necessity of preparing for Shabbat. Rather, the fast is advanced to Thursday, which is the 11th of Adar. If the 14th falls on Shabbat, it is forbidden to fast on Erev Shabbat because of the necessity of preparing for Shabbat. The primary reason for a fast day is the recital of seliḥot and raḥamim, and reciting these (instead of preparing for Shabbat) will detract from honoring the Shabbat. Honoring the shabbat is more important than a thousand fasts, for honoring the Shabbat is a commandment from the Torah, while the fast is a rabbinic decree. The Torah commandment of honoring the Shabbat takes precedence over the fast, a rabbinic decree. Hence the fast is advanced to Thursday, the 12th. If the 14th falls on Erev Shabbat, the fast is observed on Thursday, which is the 13th. This is set forth in the Mishnah. How does this occur? If it falls on a Monday, villages and cities read that day and walled towns read the next day. If it falls on Shabbat or the first day of the week, villages advance the reading to yom ha-kenisah, etc. But when the 9th of Av falls on Shabbat, the fast is postponed until after Shabbat, since this fast was instituted as a punishment. Therefore, the fast is postponed and not advanced.
From the above discussion we learn that one may not engage in a voluntarily self-afflicted fast on Erev Shabbat. Neither the community nor the individual. That is the law.Footnote 50
One of the cases discussed in this responsum is the case of the 14th of Adar falling on Shabbat. Almost certainly, this would no longer have occurred at the time this responsum was composed.Footnote 51 This suggests, as does a close reading of the responsum, that it is not describing a still current practice of fasting on the 13th. It is only interpreting M. Megillah 1:1–2, the ninth chapter of the book of Esther, and the statement of R. Samuel b. Isaac, and describing a practice of fasting on the 13th that theoretically occurred in ancient times, according to the interpretations it was offering.
With regard to the relevant she'ilta, she'ilta 79,Footnote 52 I have printed it in Appendix I. It is one of four she'iltot for Purim.
Robert Brody has suggested that the four she'iltot for Purim were probably not in the original she'iltot when it left the hands of R. Aḥai, but were composed at a later stage.Footnote 53She'ilta 79 is even more problematic than the other three. After the first few lines in Aramaic, its balance is almost entirely in Hebrew, unlike the rest of the she'iltot.Footnote 54 Also, the characteristic structure of a she'ilta, a problematic question and its resolution, is completely lacking in she'ilta 79.
Careful reading of the geonic responsum and she'ilta 79 suggests that the geonic responsum is the earlier source. It is organized and concise, and seems to reflect an attempt to record an official interpretation of M. Megillah 1:1–2.Footnote 55She'ilta 79, by contrast, seems to take for granted an already established explanation of these sections of the Mishnah, which it reiterates and comments upon. In its reiteration, she'ilta 79 leaves out certain points, making it difficult to understand without reference to the geonic responsum. Nonetheless, in some areas it is more expansive than the geonic responsum.
She'ilta 79 can be read as only reiterating interpretations of M. Megillah 1:1–2, the ninth chapter of the book of Esther, and the statement of R. Samuel b. Isaac, without describing a practice of fasting in its own time or implying that there was such a practice. But a better reading of this entire she'ilta suggests that a practice of fasting on the 13th of Adar at that time is implied. She'ilta 79 probably dates from the ninth or tenth century,Footnote 56 and it is reasonable to work with the assumption that the geonic responsum dates from the eighth or ninth century.Footnote 57
The interpretation of the word nikhalu as expressed in the geonic responsum and she'ilta 79 strays far from the word's plain sense. The root k-h-1 implies only gathering, not fasting, and it is clear from the contexts in Esther 9:2 and 9:16 that nikhalu refers to a physical gathering to fight enemies.Footnote 58 Also far from its plain sense is the interpretation of the statement of R. Samuel b. Isaac, yod-gimmel zeman kehillah la-kol hiy.Footnote 59 The plain sense of the statement is that R. Samuel b. Isaac is describing the 13th as a day on which the Jews gathered to fight.Footnote 60 He employs the word kehillah because the book of Esther uses words from this root several times in its eighth and ninth chapters, when describing the Jews’ activities on that day.
The interpretation of the term yom ha-kenisah is also removed from its plain sense. If M. Megillah 1:1–2 were referring to changing the reading to a fast day, the term we would expect it to use would be yom ha-ta‘anit. Moreover, M. Megillah 1:3 includes the following statement by R. Judah:
When [may the reading be advanced]? In a place where they enter (makom she- nikhnasin) on Monday and Thursday.
This strongly suggests that the term yom ha-kenisah at M. Megillah 1:1–2 refers to Mondays and Thursdays. Finally, an anonymous talmudic discussion at B. Megillah 4a–b understands yom ha-kenisah as a reference to Mondays and Thursdays, and states explicitly that yom ha-kenisah can occur on days such as the tenth or eleventh.Footnote 61
The critical question is what motivated these three unusual interpretations. Obviously, one possible motivation was an attempt to justify an existing practice of fasting on the 13th. But in Part VI of this article, I will suggest something entirely different for the motivation behind these unusual interpretations.
V. The Palestinian Custom of Fasting Three Days in Adar
Three sources that document a Palestinian custom of fasting three days in Adar have come to light from the Cairo Genizah. One source is a siddur fragment recording a custom of fasting on the Monday–Thursday–Monday set in Adar closest to the first of Nissan.Footnote 62 Another source is a list of fast days that records that three days of fasting for Purim were observed in Adar, even though the specific days in Adar are not provided.Footnote 63 The final source is a siddur fragment noting that three fast days are observed in Adar before Purim.Footnote 64
Additionally, Massekhet soferim refers to a Palestinian custom of fasting on a Monday-Thursday-Monday set in Adar. Until recently, Massekhet soferim was viewed as a Palestinian compilation dating from the eighth century.Footnote 65 Scholars have now begun to regard it as a work compiled outside of Palestine, in an area under Palestinian influence such as Italy or Byzantium.Footnote 66 Moreover, the work was probably not completed until the ninth or tenth century, even though the material in the first nine of its twenty-one chapters is older.Footnote 67 Its reliability with respect to Palestinian customs has also been called into question.Footnote 68
Massekhet soferim includes the following passages in its seventeenth and twenty-first chapters:
שלשת ימי הצום אין מתענין אותן רצופין אלא פרודין שני וחמישי ושני ורבותינו שבארץ ישראל נהגו להתענות אחר ימי הפורים מפני ניקנור Footnote 69וחביריו ועוד שמאחרין בפורענות ואין מקדימין.
The three fast days are not fasted consecutively but separately: Monday, Thursday, and Monday. The Sages of the land of Israel were accustomed to fast after the days of PurimFootnote 70 because of Nikanor and his friends, and also because punishments are postponed and not advanced.
מנהג רבותינו שבמערב להתענות שלשת ימי צום מרדכי ואסתר פרודות ולאחר פורים שני וחמישי ושני. ולמה אין מתענין אותן בחדש ניסן …לקרוא צום בציבור אסור עד שיעבור ניסן.Footnote 71
The custom of the Sages of the West is to fast the three fast days of Mordecai and Esther separately, and after Purim, on Monday, Thursday, and Monday. Why are they not observed in the month of Nissan? … To call a public fast is forbidden until Nissan passes.Footnote 72
It is almost certain that the Palestinian custom of fasting three days in Adar was established to commemorate the three days of fasting initiated by Esther.
With regard to the antiquity of this custom, there is documentation showing that it was a practice among many Jews in Palestine in the tannaitic and amoraic periods to fast regularly on Monday and Thursday.Footnote 73 The institution of a fast on a Monday–Thursday–Monday cycle in Adar would have been a natural extension of such a practice.Footnote 74 Admittedly, however, there is no reference in either the Jerusalem or Babylonian Talmud to a Palestinian custom of fasting on a Monday–Thursday–Monday cycle in connection with Adar or Purim.Footnote 75
VI. Approaches to the Origin of the Fast of the 13th
One approach to the origin of the fast of the 13th of Adar (“the first approach”) is to regard it as a post-talmudic custom designed to commemorate the three days of fasting initiated by Esther in Nissan.Footnote 76 An early authority who seems to take this approach is Maimonides (1138–1204).Footnote 77 Those who follow this approach assume that those who started the custom chose to move the commemoration from Nissan to Adar, perhaps because of a prohibition on fasting in Nissan, and chose to limit the fast to one day. The idea of commemorating these fasts may have been the Babylonian community's response to a possibly earlier Palestinian custom of commemorating them. More likely, the motivation may simply have been the Babylonian community's own desire to commemorate this set of effective fasts described in the Bible.Footnote 78
In the first approach, one might view the geonic responsum included in Midrash Tanḥuma as motivated by an attempt to justify an existing custom to fast on the 13th.Footnote 79
One weakness with the first approach is that neither Talmud records a prohibition on fasting in Nissan.Footnote 80 If the leaders of Babylonian Jewry in the early or middle geonic period wished to institute a commemoration of the fasts initiated by Esther and wanted to limit the commemoration to one day, it does not seem that they were facing any prohibition to fast in Nissan.Footnote 81 All that was necessary was for them to set up a commemorative fast on the 13th of Nissan.Footnote 82 But admittedly, even without such a prohibition, the leaders of Babylonian Jewry may have decided it was more appropriate to observe the commemoration on a day adjacent to Purim.Footnote 83
The more serious weakness with the first approach is that the idea that fasting on the 13th of Adar is a post-talmudic custom designed to commemorate the fasts initiated by Esther is not found in any of the geonic sources.Footnote 84
Rather, when the geonic sources express or imply an origin for the fast, these sources consistently express or imply that the fast is a rabbinic obligation dating from the biblical period. Specifically:
• The geonic responsum included in Midrash Tanḥuma uses the phrase ve-gazru ta‘anit to describe what occurred in the year of the threat, and describes the practice of fasting as a de-rabbanan. The import of these statements, taken together, is that in the year of the threat a decree was enacted that bound future generations.Footnote 85
• R. Se‘adyah, in his siddur, mentions the fast along with the four other rabbinic fasts from the biblical period, as if to say that the origin of this fast is found there as well. He writes, in a section on seliḥot:
I would like to record … 27 additional seliḥot: 11 of these for the Ninth of Av, 2 for the Seventeenth of Tammuz, 2 for the Third of Tishrei, 2 for the Tenth of Tevet, 3 for the Fast of the Megillah (צום אלמגלה), and 7 for an ordinary fast….Footnote 86
Also, in its plainest sense, the term צום אלמגלה means the fast referred to in the Megillah.Footnote 87
• An anonymous geonic responsum takes the position that, in a leap year, one fasts even on the 13th of Adar I.Footnote 88 Most likely, it takes this position because it views fasting on the 13th of Adar as an obligation, based on the geonic interpretation of nikhalu. If it viewed the fast as a post-talmudic custom designed to commemorate fasting that took place in Nissan, a fast on the 13th of Adar II would almost certainly have been viewed as sufficient.
• Sefer ha-mikẓo‘ot,Footnote 89 a work of unknown authorship from the late geonic period, includes the statement that fasting on the 13th is an obligation ordained by ha-kadosh barukh hu. The passage reads:
וחייבינהו הקדוש ברוך הוא לישראל לענויי נפשייהו בשלשה עשר Footnote 90דאמר רבי שמואל בר רב יצחק שלשה עשר זמן קהילה לכל הוא שנאמר
נקהלו היהודים.למה נקרא יום קהילה יום תענית יום כניסה שמתכנסין בו ישראל ויושבין בתענית ומבקשים רחמים שנאמר דברי הצומות וזעקתם.
The Holy One Blessed Be He obligated Israel to afflict themselves on the 13th, as R. Samuel b. R. Isaac said: the 13th is a day of gathering for all, as it is written “the Jews gathered themselves” (Esther 9:2). Why is it called yom kehillah, yom ta‘anit, yom kenisah?Footnote 91 Because Israel gathers on this day, and engages in fasting, and requests mercy, as it is written “the matters of the fasts and their outcry” (Esther 9:31).
The intent of the author is probably that the fast is an obligation based on a biblical verse (the Divine word) and that this obligation commenced in the biblical period. This is not the language of someone expressing the view that the fast is a post-talmudic custom.
Finally, if one reviews all the Babylonian geonic references to the fast of the 13th of Adar, as collected in Parts III and IV, words such as nahagu, nohagin, or minhag are not used with reference to the fast.Footnote 92
It can be argued that the name of the fast, Ta‘anit Esther, is consistent with the approach that the fast commemorates the fasts initiated by Esther. But if one looks at the names for the fast in the geonic period in Babylonia and its environs, R. Natronai calls the fast תענית פורים, R. Se‘adyah calls it צום אלמגלה, and Al-Biruni (a Muslim writing in the year 1000) calls the day “the fasting of Alburi” (Purim).Footnote 93
Only one Babylonian geonic source might conceivably have referred to the day as Ta‘anit Esther: the expanded version of Seder parshiyyot shel yamim tovim ve-haftarot shelahen.Footnote 94 This source probably dates from the late ninth or early tenth century, and includes a shortened version of the responsum of R. Natronai that referred to the fast. There are only three manuscripts of the expanded version of Seder parshiyyot, none of which was actually copied in geonic Babylonia.Footnote 95 Two of the manuscripts read תענית אסתר,Footnote 96 while one reads תענית פורים.Footnote 97 Since R. Natronai's original responsum called the fast Ta‘anit Purim, it seems likely that the manuscript of Seder parshiyyot that reflects this reading has preserved the original and that the other reading originated when a copyist altered the name to fit the name for the fast prevailing in his region.Footnote 98
As the first approach is not consistent with the statements about the fast that are found in the geonic sources, I would like to suggest another approach to the origin of the fast (“second approach”). This approach has not been suggested elsewhere.Footnote 99 But it is largely consistent with what is found in the geonic sources, although it does raise some issues of its own.
In this second approach, the custom to fast on the 13th arose as a result of the unusual interpretations expressed in the geonic responsum included in Midrash Tanḥuma. As explained in Part IV, yom ha-kenisah in M. Megillah 1:1–2 was interpreted as a reference to the 13th of Adar as a fast day (the day on which Jews gather to fast). The statements in the ninth chapter of the book of Esther that the Jews gathered themselves (נקהלו) on the 13th of Adar were interpreted as indicating that the Jews fasted on the 13th of Adar in the year of the threat. Finally, the statement of R. Samuel b. Isaac, י”ג זמן קהילה לכל היא, was also interpreted as indicating that the Jews fasted on the 13th of Adar in the year of the threat.
A claim that the custom to fast on the 13th arose as a result of the above unusual interpretations is justifiable only if one can suggest a reason for the unusual interpretations other than to justify an already existing practice to fast that day. Such a reason can easily be suggested, based on a careful reading of the responsum included in Midrash Tanḥuma and an understanding of the issues of halakha that were subject to major dispute in the geonic period. The responsum included in Midrash Tanḥuma was from Babylonian geonim. It is reasonable to work with the assumption that it dates from the eighth or ninth century.Footnote 100 As I will document shortly, a major issue of halakha in this period was the permissibility of fasting on Shabbat.Footnote 101
The unusual interpretations can be explained if we assume that the authors were responding to and opposing widespread practices of fasting on Shabbat and Erev Shabbat in their time. Interpreting yom ha-kenisah the way they did enabled them to cite M. Megillah 1:1–2 as a source to prohibit fasting on those days. In their interpretation, the reading of the Megillah for the villagers is allowed to be advanced because the date of the observance of the fast day is being advanced. It is being advanced due to a prohibition to fast on Shabbat and Erev Shabbat that they were reading into the Mishnah.
One clue that the authors were responding to existing practices of fasting on Shabbat and Erev Shabbat is that the responsum includes a polemical line stressing the importance of honoring the Shabbat:
If the 14th falls on the first day of the week, it is forbidden to fast on Shabbat. It is also forbidden to fast on Erev Shabbat, because of the necessity of preparing for Shabbat. Rather, the fast is advanced to Thursday, which is the 11th of Adar. If the 14th falls on Shabbat, it is forbidden to fast on Erev Shabbat because of the necessity of preparing for Shabbat. The primary reason for a fast day is the recital of seliḥot and raḥamim, and reciting these (instead of preparing for Shabbat) will detract from kavod Shabbat. Honoring the Shabbat is more important than a thousand fasts, for honoring the Shabbat is a commandment from the Torah, while the fast is a rabbinic decree. The Torah commandment of honoring the Shabbat takes precedence over the fast, a rabbinic decree… .Footnote 102
In the eighth and ninth centuries, there was much discussion about the issue of fasting on Shabbat in the context of fasting on the Shabbat before Yom Kippur. One of the many Palestinian practices that the letter of Pirkoy ben BaboyFootnote 103 criticized was their practice of fasting on Rosh Hashanah and the Shabbat before Yom Kippur.Footnote 104 Those who followed this practice did so as part of a practice to fast for the entire ten days of repentance.Footnote 105 Also, R. Yehudai GaonFootnote 106 is recorded to have opposed fasting on the Shabbat before Yom Kippur.Footnote 107 He is also recorded to have opposed fasting on the two days of Rosh Hashanah.Footnote 108 It is possible that his statements were made in response to the Palestinian practice. But it is more likely that he was responding to a Babylonian practice of fasting for the entire ten days of repentance.Footnote 109
Another context where the issue of fasting on Shabbat arose was the context of a regular Shabbat. Pirkoy ben Baboy criticizes a Palestinian practice of fasting on a regular Shabbat.Footnote 110 It is possible that he is referring to small numbers of individuals who fasted on Shabbat for exceptional reasons. But it seems more likely from the context that he is referring to larger numbers of Palestinian Jews fasting on Shabbat, probably as a form of repentance or piety.Footnote 111 Pirkoy employs strong language in his criticism of those who followed this course:
וכל היושב בתענית בשבת ויעשה אותה כחול במזיד אין לו חלק לא בעולם הזה ולא לעולם הבא שכך כת׳ מחלליה מות יומת מת בעולם הזה וימות לעולם הבא … מחלליה אינו אלא מי שאינו מענגה ועושה אותה כחול.
Whoever engages in fasting on Shabbat and wilfully treats it as an ordinary day does not have a portion in this world nor in the world to come, as it is written (Exodus 31:14) “those who profane it (meḥalaleha) shall surely die (mot yumat).” [The repetition teaches that] they die in this world and will die in the next world… . Meḥalaleha means one who does not treat it with delight but treats it as an ordinary day.Footnote 112
Strikingly, Pirkoy uses almost the same language as the geonic responsum included in Midrash Tanḥuma:
Footnote 113.וגדול עינוג שבת אחד יותר ממקריב אלף קרבנות ומאלף תענית
One who delights in one Shabbat is greater than one who sacrifices a thousand sacrifices and (fasts) a thousand fasts.
The practices that the authors of the unusual interpretations could have been responding to could have been: (1) the practice in Babylonia of fasting on the Shabbat before Yom Kippur; (2) practices in Babylonia of fasting on Shabbat as a form of repentance or piety, or by those whose ideal Shabbat consisted of studying or praying all day,Footnote 114 or by those who enjoyed fasting; or (3) practices of fasting on Shabbat in Palestine in the above contexts.Footnote 115
It is also possible that the authors of the unusual interpretations were motivated mainly by opposition to a widespread practice of fasting on Erev Shabbat. It was in the context of giving the reason for the prohibition to fast on Erev Shabbat that the responsum used its polemical language. Moreover, a variety of early sources already existed reflecting a prohibition to fast on Shabbat.Footnote 116 A mishnaic source reflecting a prohibition to fast on Erev Shabbat would be new (outside of the limited context of ’anshei ma‘amad).Footnote 117
In the second approach, I am suggesting that the unusual interpretations expressed in the geonic responsum arose out of one or more of these polemical motivations, leading M. Megillah 1:1–2 to be interpreted as implying a prohibition to fast on Shabbat and Erev Shabbat. A new “tradition” about an ancient fast on the 13th of Adar was the result.
The unusual interpretations of nikhalu at Esther 9:1–2 and/or 9:16–17, and of the statement of R. Samuel b. Isaac, are just ancillary; they are merely attempts to support the claim that a fast was observed on the 13th in the year of the threat, so that yom ha-kenisah in M. Megillah 1:1–2 might refer to a fast day on the 13th.
The authors of the unusual interpretations were not motivated by an attempt to justify an existing custom to fast on the 13th, as there was no such custom.
Although the second approach is consistent with the geonic statements about the fast of the 13th of Adar,Footnote 118 it does have some weaknesses. The first weakness is that if the fast originated in the manner suggested, one should perhaps only find evidence for the fast in areas that prohibited fasting on Shabbat (except in cases of ta‘anit ḥalom).Footnote 119 However, R. Natronai refers to the fast with seeming approval,Footnote 120 and at the same time permits fasting on the Shabbat before Yom Kippur.Footnote 121
One might respond that after the interpretation of M. Megillah 1:1–2 arose, and the practice of fasting on the 13th commenced based on this interpretation, the underlying motivations that gave rise to the interpretation may no longer have mattered. An alternative response is that R. Natronai may have been aware of and in essential agreement with the motivations behind the geonic interpretation of M. Megillah 1:1–2. However, he might have believed that the policy of prohibiting fasting on Shabbat was entirely inapplicable to the Shabbat before Yom Kippur. In his responsum that permitted fasting on the Shabbat before Yom Kippur, R. Natronai stated clearly that the ten days of repentance were different from the rest of the year.Footnote 122
A second weakness is that the language of the geonic responsum in Midrash Tanḥuma might be read as describing a practice of fasting on the 13th in its time. But this is not the simplest reading of the responsum, which seems only to offer an interpretation of M. Megillah 1:1–2, the ninth chapter of the book of Esther, and the statement of R. Samuel b. Isaac.Footnote 123
The most serious weakness is the argument that geonim would unlikely have polemically interpreted a Mishnah to such an extent that their interpretation would result in the observance of a new (assumed to be ancient) fast day.
A response is that the authors of the interpretation may have convinced themselves of the truth of their interpretation. Far more difficult mishnaic interpretations than this were adopted by Amoraim throughout the Talmud. Although the interpretation was not a plain-sense interpretation of nikhalu in the book of Esther, it was plain sense enough as an interpretation of yom ha-kenisah Footnote 124 and M. Megillah 1:1–2.Footnote 125 It was also plain sense enough as an interpretation of R. Samuel b. Isaac's statement.
An alternative response is that those who composed the interpretation did not foresee that a new fast day would later be observed as a result of their words, even though the terms ve-gazru ta‘anit and ta‘anit de-rabbanan, taken together, imply that a decree was enacted in the year of the threat, and was binding for future generations.
A third response is that the interpretation may have initially arisen orally, without all the elements and terms later included in the written responsum. The authors of the original version of the interpretation did not foresee how it would eventually develop and imply that a decree was enacted in the year of the threat, and was binding for future generations.
• • •
If one believes that there was a preexisting practice to fast on the 13th which the geonic interpretation of M. Megillah 1:1–2 was trying to justify, then a third approach to the origin of the fast might be suggested.Footnote 126 In this approach, the fast originated as a custom.Footnote 127 But once the above geonic interpretation became widespread, the original reason for the fast and its true period of origin were forgotten, and the fast came to be treated as a rabbinic obligation from the biblical period.Footnote 128
The most reasonable explanations for the origin of a custom to fast on the 13th of Adar would be: (1) a desire to commemorate the three days of fasting initiated by Esther;Footnote 129 (2) a desire to commemorate the fasts throughout the provinces referred to at Esther 4:3; (3) a desire to commemorate the 13th of Adar as the day originally planned for the destruction of the Jews by Haman;Footnote 130 and (4) a desire to commemorate the 13th of Adar as a traumatic day in the year of the threat, the first and main day of the battle.Footnote 131
But if there was an earlier custom to fast on the 13th that the geonic responsum was trying to justify, it can be argued that the fast on the 13th would have been more widespread than is reflected in the sources. The custom is not included in the Halakhot gedolot, and its inclusion in Seder Rav ‘Amram probably dates only from the time of the rishonim.Footnote 132 This suggests that the custom originated at a later stage, and seems more consistent with the approach that it started as a consequence of the geonic interpretation expressed in Midrash Tanḥuma (“second approach”), and not before it.Footnote 133
Finally, several interesting explanations for the origin of the fast that have been suggested over the centuries deserve mention:
• A fast was set up on the 13th, the day immediately before the holiday, to remind us that God answers the prayers of those who turn to Him, just as He answered the prayers of the Jews that year, when they fasted for three days in Nissan.Footnote 134
• The 13th was a day of fighting in the year of the threat, whereas the next day the Jews were victorious and rested. The commemorative fast and holiday were enacted at the same time to model the fact that the Jews went from distress to salvation that year.Footnote 135
• The Jews fasted on the 13th in the year of the threat, and it would not be proper to accept the joyous events of the year of Purim without also accepting the difficult events.Footnote 136
• A fast was set up on the 13th to prevent satanic forces from being able to accuse Jews of overindulgence on Purim. By fasting on the 13th, Jews show that when we drink wine the next day, it is only as part of our divine service, and not to satisfy our own urges. Footnote 137
• A fast on the 13th was established to make sure that people come eagerly to hear the Megillah reading on the night of the 14th.Footnote 138
VII. Summary and Conclusions
The practice of fasting on the 13th of Adar originated in geonic Babylonia.Footnote 139 The responsum of R. Natronai is the earliest Babylonian geonic source that refers to the fast by a name, calling it Ta‘anit Purim. Of the four sources in the geonic period from Babylonia and its environs that refer to the fast by a name, most likely none of them calls it Ta‘anit Esther.Footnote 140
When the geonic sources express or imply something about the origin of the fast, they consistently state or imply that the fast is a rabbinic obligation dating from the biblical period. The approach most consistent with the geonic sources is that the fast arose as a consequence of an interpretation of M. Megillah 1:1–2 (“second approach”). It has been suggested that the authors of the interpretation were responding to and opposing widespread practices of fasting on Shabbat and Erev Shabbat. This led them to interpret M. Megillah 1:1–2 to imply a prohibition of fasting on Shabbat and Erev Shabbat. The result was a new “tradition” about an ancient fast on the 13th of Adar. There had not been a practice of fasting on the 13th at the time the geonic interpretation of M. Megillah 1:1–2 originated.
Finally, we have documented four sources that refer to a Palestinian custom of fasting for three days in Adar. This custom almost certainly was a commemoration of the three days of fasting initiated by Esther.

Appendix II: The Prohibition to Fast on the Day before Purim
Purim is included in the list of Megillat ta‘anit holidays, and is listed as one of the more stringent ones, upon which both eulogizing and fasting were prohibited. In the case of such holidays, the Mishnah in M. Ta‘anit 2:8 instructs that a prohibition existed to fast on the day before the holiday as well. This was according to the view of the tanna kamma, and according to the other view recorded in the Mishnah, that of R. Yose.Footnote 149 The Talmud records a third tannaitic view, that of R. Simeon b. Gamliel, who took the position that there were no prohibitions on days surrounding Megillat ta‘anit holidays. The Talmud (Ta‘anit 18a) records traditions in the name of Rav and R. Yoḥanan that the halakha follows R. Yose, and in the name of Samuel that the halakha follows R. Simeon b. Gamliel. In such a case, the halakha would normally follow Rav and R. Yoḥanan.Footnote 150 All agree that Purim survived the discontinuance of Megillat ta‘anit. If there was a prohibition to fast on the day before Purim, we need to explain how a fast on the 13th of Adar could ever have arisen.Footnote 151
An answer was suggested in Part VI. If the fast arose as a consequence of the geonic interpretation recorded in Midrash Tanḥuma, the fast would have been viewed as a resumption of an ancient obligation to fast on the 13th, based on a biblical verse. This would have easily overridden any possible prohibition to fast.Footnote 152
But most of the rishonim give other answers to the question. The main responses are as follows:Footnote 153
1. Even though Purim anḍ Hanukkah themselves survived the discontinuance of Megillat ta‘anit, the prohibitions regarding surrounding days ended with the discontinuance of Megillat ta‘anit.Footnote 154
2. As stated explicitly in both Talmuds, the prohibitions regarding surrounding days were meant to strengthen the observance of rabbinic holidays. Although included in the list of Megillat ta‘anit holidays, Purim differed in that it was a holiday of biblical origin. The prohibitions regarding surrounding days were never applicable to this day.
3. Once it was decided that the observance of Yom Nikanor was to be cancelled and that the 13th of Adar should no longer be a holiday, it would have made little sense to invoke a new prohibition merely because the day happened to be the day before another holiday.Footnote 155
4. The prohibitions regarding fasting on surrounding days of Megillat ta‘anit holidays only applied to fasts observed out of distress. The fast on the 13th of Adar celebrates miraculous deliverance, and is a fast of joy.
A few rishonim take the approach that the halakha follows R. Simeon b. Gamliel.Footnote 156
Appendix III: The View of R. Jacob Tam
The view of R. Tam is often cited in connection with the origin of the fast of the 13th A few matters in connection with his view require discussion.Footnote 157
In the Rashba, Ritba,Footnote 158 and others, R. Tam expresses essentially the same interpretation of zeman kehillah la-kol hiy as found in the geonic responsum included in Midrash Tanḥuma and she'ilta 79. But the unusual interpretation of yom ha-kenisah is not discussed or alluded to. But the way the view of R. Tam is cited in one place in the Rosh, R. Tam seems to be following the unusual interpretation of yom ha-kenisah. In his commentary to Meg. 2a,Footnote 159 the Rosh writes that, according to R. Tam, zeman kehillah la-kol hiy meant that everyone gathers for Ta‘anit Esther, and the villagers come to the cities. Footnote 160 Similar language is used by the Tur.Footnote 161 The way R. Tam is cited in the Mordekhai also suggests that R. Tam was following the unusual interpretation of yom ha-kenisah. Footnote 162
The view of R. Tam is cited by the Rosh and many of the rishonim as if it is his own. But the fact that R. Tam follows at least one of the unusual interpretations found in the geonic responsum and she'ilta 79 suggests that he had at least one of these sources in front of him. Several sources state that R. Tam used the She'iltot here,Footnote 163 but it is possible that he had the geonic responsum before him as well (or instead).
In his commentary on Meg. 2a, the Rosh writes:
מכאן נראה לרבינו ת”ם סעד לתענית אסתר שאנו עושין כמושעשו בימי מרדכי ואסתר …
From here,Footnote 164 it appears to Rabbeinu Tam that we have a support for Ta‘anit Esther that we observe, as they observed it in the days of Mordecai and Esther.
This sounds like R. Tam's position might be that, after the year of the threat, the fast on the 13th was not observed until it was instituted again in later times. But the Rosh writes elsewhere that, according to the view of R. Tam, Ta‘anit Esther was an enactment of the Sages even before Megillat ta‘anit was annulled.Footnote 165 Here, the Rosh has not attributed to R. Tam the position that the fast was observed every year after the year of the threat, but has attributed to him the position that the fast was observed in ancient times. The Rosh does not state how R. Tam reconciled his position with the observance of Yom Nikanor.
Finally, R. Tam attempts to support the interpretation that the Jews fasted on the 13th at the time of their battle with their Persian enemies by pointing to the tradition that the Jewish people fasted when they battled Amalek in the time of Moses.Footnote 166 He is the earliest authority recorded to have made this point, and it is repeated by many others.Footnote 167
