Mishneh Torah — Fasts (Ta'aniyot) הלכות תעניות, Chapter 3

The full Hebrew text of Mishneh Torah, Fasts (Ta'aniyot), Chapter 3, with English translation by Maimonides (Rambam).

הֲרֵי שֶׁלֹּא יָרְדוּ לָהֶם גְּשָׁמִים כָּל עִקָּר מִתְּחִלַּת יְמוֹת הַגְּשָׁמִים. אִם הִגִּיעַ שִׁבְעָה עָשָׂר בְּמַרְחֶשְׁוָן וְלֹא יָרְדוּ גְּשָׁמִים מַתְחִילִין תַּלְמִידֵי חֲכָמִים בִּלְבַד לְהִתְעַנּוֹת שֵׁנִי וַחֲמִישִׁי וְשֵׁנִי. וְכָל הַתַּלְמִידִים רְאוּיִין לְכָךְ:

[We should adhere to the following procedure when] no rain at all has descended from the beginning of the rainy season onward: 6a relates that the rainy season in Eretz Yisrael begins in the month of Marcheshvan. The third of the month is considered to be the earliest time rain can be expected to descend.In other lands, such fasts should be held when, ע"ל, they are necessary according to the local needs and climate (Halachah 10; Shulchan Aruch, Orach Chayim 575:9). If the seventeenth of Marcheshvan arrives and no rains have descended, the Torah scholars should begin to fast, [starting on] a Monday [and continuing on] the [following] Thursday, and the [following] Monday. (Orach Chayim 575:1) emphasizes that these fasts are considered individual fasts and not communal fasts. All students [of the Torah] are fit to accept these [fasts] upon themselves. 10b suggests that all students of the Torah accept these fasts if possible.

הִגִּיעַ רֹאשׁ חֹדֶשׁ כִּסְלֵו וְלֹא יָרְדוּ גְּשָׁמִים בֵּית דִּין גּוֹזְרִין שָׁלֹשׁ תַּעֲנִיּוֹת עַל הַצִּבּוּר שֵׁנִי וַחֲמִישִׁי וְשֵׁנִי. וּמֻתָּרִין בָּהֶן לֶאֱכל וְלִשְׁתּוֹת בַּלַּיְלָה. וְאַנְשֵׁי מִשְׁמָר אֵין מִתְעַנִּין עִמָּהֶן מִפְּנֵי שֶׁהֵן עֲסוּקִין בַּעֲבוֹדָה. וְכָל הָעָם נִכְנָסִים לְבָתֵּי כְּנֵסִיּוֹת וּמִתְפַּלְּלִין וְזוֹעֲקִין וּמִתְחַנְּנִין כְּדֶרֶךְ שֶׁעוֹשִׂין בְּכָל הַתַּעֲנִיּוֹת:

If Rosh Chodesh Kislev arrives without the rains having descended, the court should decree three communal fasts, [starting on] a Monday, [and continuing on] the [following] Thursday, and the [following] Monday. It is permitted to eat and drink at night. The men serving in the [weekly] priestly watch 3:9, which states that the prophet Samuel and King David ordained 24 priestly watches, which rotated in the Temple service. Each week, a different watch would serve. should not fast with them because they are involved in the Temple service. 2:6).On these days, the entire people should enter the synagogue, pray, cry out [to God], is recited in the Shemoneh Esreh, and other supplicatory prayers are recited. and make supplications as is customary on all fasts.

עָבְרוּ אֵלּוּ וְלֹא נַעֲנוּ בֵּית דִּין גּוֹזְרִין שָׁלֹשׁ תַּעֲנִיּוֹת אֲחֵרוֹת עַל הַצִּבּוּר שֵׁנִי וַחֲמִישִׁי וְשֵׁנִי. וּבְשָׁלֹשׁ אֵלּוּ אוֹכְלִין וְשׁוֹתִין מִבְּעוֹד יוֹם כְּמוֹ שֶׁעוֹשִׂין בְּצוֹם כִּפּוּר. וְאַנְשֵׁי מִשְׁמָר מִתְעַנִּין מִקְצָת הַיּוֹם וְלֹא מַשְׁלִימִין. וְאַנְשֵׁי בֵּית אָב וְהֵם הָעוֹסְקִין בַּעֲבוֹדָה בְּאוֹתוֹ הַיּוֹם לֹא יִהְיוּ מִתְעַנִּים כָּל עִקָּר. וְכָל תַּעֲנִית שֶׁאוֹכְלִין בָּהּ מִבְּעוֹד יוֹם אִם אָכַל וּפָסַק וְגָמַר שֶׁלֹּא לֶאֱכל אֵינוֹ חוֹזֵר וְאוֹכֵל אַף עַל פִּי שֶׁיֵּשׁ שְׁהוּת בַּיּוֹם:

If these [fasts] pass without [their prayers] being answered, 1:6), the Rambam teaches us a lesson in the service of God. It could have said, "If these fasts pass without rain having descended." The Rambam and the Mishnah, however, want to emphasize that the ultimate reason why rain descends or does not descend is not dependent on natural factors, but rather on God's mercies. the court should decree an additional three communal fasts. that read "[starting on] a Monday, [and continuing on] the [following] Thursday, and the [following] Monday," and other texts read "[starting on] Thursday, [and continuing on] the [following] Monday, and the [following] Thursday."The difference between these two versions depends on the difference of opinion mentioned in the commentary on Chapter 1, Halachah 5, concerning the question: Should the second series of fasts begin on a Thursday or not? On these fasts, we eat and drink while it is still day [on the day before the fast], as on the fast of Yom Kippur. 575:2, however, explains that unlike Yom Kippur (Hilchot Sh'vitat Esor 1:6), there is no obligation to begin the fast before sunset.The men serving in the [weekly] priestly watch should fast for part of the day, but should not complete the fast. The men of the beit av - those individuals who are involved in the Temple service that day - should not fast at all.On a fast for which we are required to cease eating while it is still day, once a person has ceased eating and decided not to eat any more, he may not change his mind and eat, even though there is still time during the day. differ with the Rambam on this point and maintain that as long as one has not made an explicit statement to the fact that one has accepted the fast, one is allowed to change one's mind and eat. The rationale for their ruling is that, as explained above, on these fasts, in contrast to Yom Kippur, there is no obligation to begin the fast before sunset.With regard to the laws of Tish'ah B'Av - and from there we can extrapolate to the instance at hand - the Shulchan Aruch (Orach Chayim 553:1) accepts the Ramban's ruling. The Mishneh Berurah 553:2, however, states that a mental resolve to accept the fast is also sufficient to cause one to be forbidden to eat further.

בְּשָׁלֹשׁ תַּעֲנִיּוֹת אֵלּוּ כָּל הָעָם אֲסוּרִין בַּעֲשִׂיַּת מְלָאכָה בַּיּוֹם וּמֻתָּרִין בַּלַּיְלָה. וַאֲסוּרִין בִּרְחִיצַת כָּל הַגּוּף בְּחַמִּין אֲבָל פָּנָיו יָדָיו וְרַגְלָיו מֻתָּר. לְפִיכָךְ נוֹעֲלִין אֶת הַמֶּרְחֲצָאוֹת. וַאֲסוּרִין בְּסִיכָה. וְאִם לְהַעֲבִיר אֶת הַזֻּהֲמָה מֻתָּר. וַאֲסוּרִין בְּתַשְׁמִישׁ הַמִּטָּה. וּבִנְעִילַת הַסַּנְדָּל בָּעִיר אֲבָל בַּדֶּרֶךְ מֻתָּר לִנְעל. וּמִתְפַּלְּלִין בְּבָתֵּי כְּנֵסִיּוֹת וְזוֹעֲקִין וּמִתְחַנְּנִין כִּשְׁאָר תַּעֲנִיּוֹת:

On these three fasts, all people are forbidden to perform work during the day, 12b brings support for this concept from the exegesis of Joel 2:15: "Sanctify the fast day; call an assembly, and collect the elders." The word for "assembly," עצרה, resembles the Biblical name for the holiday of Shavuot, עצרת. Just as it is forbidden to work on Shavuot, so too, it is forbidden to work on a fast day. but they are permitted during the [previous] night., continues using exegesis to show that, in contrast to Shavuot, working on the night of a fast day is permitted. It is forbidden for a person to wash his entire body in hot water, 575:3). but one may wash one's face, hands, and feet.). For this reason, the bathhouses are closed.It is forbidden to anoint oneself. One may, however, do so to remove filth. 575:7). Sexual relations are forbidden, 575:8). as is wearing shoes in a city. One may, however, wear shoes on a journey. We pray in the synagogues, cry out [to God], and make supplications as is customary on all fasts.

עָבְרוּ אֵלּוּ וְלֹא נַעֲנוּ בֵּית דִּין גּוֹזְרִין שֶׁבַע תַּעֲנִיּוֹת אֲחֵרוֹת עַל הַצִּבּוּר שֵׁנִי וַחֲמִישִׁי וְשֵׁנִי וַחֲמִישִׁי וְשֵׁנִי וַחֲמִישִׁי וְשֵׁנִי. וּבְאֵלּוּ הַשֶּׁבַע בִּלְבַד עֵבָּרוֹת וּמֵינִיקוֹת מִתְעַנּוֹת אֲבָל בִּשְׁאָר הַתַּעֲנִיּוֹת אֵין עֵבָּרוֹת וּמֵינִיקוֹת מִתְעַנּוֹת. וְאַף עַל פִּי שֶׁאֵינָן מִתְעַנּוֹת אֵין מְעַנְּגוֹת עַצְמָן בְּתַפְנוּקִים אֶלָּא אוֹכְלוֹת וְשׁוֹתוֹת כְּדֵי קִיּוּם הַוָּלָד:

If these [fasts] pass without [their prayers] being answered, the court decrees another seven communal fasts, [beginning on the next] Monday, [and continuing as follows]: Thursday, Monday, Thursday, Monday, Thursday, and Monday.It is only on these seven fasts 14a, does not consider the nature of the situation during the first two sets of fasts serious enough to warrant that these women fast. During these seven fasts, in contrast, the drought has become a real danger. Hence, they are also required to fast.This ruling is not accepted by many other authorities. Most follow Rashi's interpretation of the passage, which requires these women to fast during the second set of three fasts only. The rationale for that ruling is that he feels that the drought has already become serious enough to warrant their fasting during the second set of three fasts. In principle, these women should also fast during the final seven fasts, but the Rabbis felt that such a long period of fasting would be too taxing for them. Hence, they restricted their fasts to the second set alone. This is the ruling quoted by the Shulchan Aruch (Orach Chayim 575:5). that pregnant and nursing women are required to fast. [On the other fast days,] although they are not obligated to fast,), "It is forbidden for them to be stringent with themselves and fast." they should not indulge in delicacies. Instead, they should eat only what is necessary to maintain their babies.

וּבְשֶׁבַע תַּעֲנִיּוֹת אֵלּוּ אַנְשֵׁי מִשְׁמָר מִתְעַנִּין וּמַשְׁלִימִין. וְאַנְשֵׁי בֵּית אָב מִתְעַנִּין מִקְצָת הַיּוֹם וְלֹא מַשְׁלִימִין. וְכָל דָּבָר שֶׁהוּא אָסוּר בְּשָׁלֹשׁ אֶמְצָעִיּוֹת אָסוּר בְּאֵלּוּ הַשֶּׁבַע הָאַחֲרוֹנוֹת:

On these seven fasts the men serving in the [weekly] priestly watch should fast for the entire day. The men of the beit av should fast for a portion of the day, but should not complete their fast.) were obligated to fast for a portion of the day. All the prohibitions in force during the second set of fasts are also in force during these last seven fasts.

וִיתֵרוֹת אֵלּוּ. שֶׁבָּהֶן בִּלְבַד מַתְרִיעִין וּמִתְפַּלְּלִין בִּרְחוֹב הָעִיר. וּמוֹרִידִין זָקֵן לְהוֹכִיחַ לָעָם כְּדֵי שֶׁיָּשׁוּבוּ מִדַּרְכָּם. וּמוֹסִיפִין שֵׁשׁ בְּרָכוֹת בִּתְפִלַּת שַׁחֲרִית וּבִתְפִלַּת מִנְחָה וְנִמְצְאוּ מִתְפַּלְּלִין כ"ד בְּרָכוֹת. וְנוֹעֲלִין אֶת הַחֲנֻיּוֹת. וּבַשֵּׁנִי מַטִּין לְעֵת עֶרֶב וּפוֹתְחִין אֶת הַחֲנֻיּוֹת. אֲבָל בַּחֲמִישִׁי פּוֹתְחִין כָּל הַיּוֹם מִפְּנֵי כְּבוֹד הַשַּׁבָּת. וְאִם יֵשׁ לַחֲנוּת שְׁנֵי פְּתָחִים פּוֹתֵחַ אֶחָד וְנוֹעֵל אֶחָד וְאִם יֵשׁ לַחֲנוּת אִצְטַבָּה פּוֹתֵחַ כְּדַרְכּוֹ בַּחֲמִישִׁי וְאֵינוֹ חוֹשֵׁשׁ:

There are additional dimensions [of severity] to these [fasts]: it is on these alone that we sound the trumpets, pray in the street of the city, call on an elder to admonish the people [and motivate] them to repent from their [evil] ways, add six blessings in the morning and afternoon prayers). - thus, we recite twenty-four blessings, 2:2), which refers to the era before the nineteenth blessing was added to the daily Shemoneh Esreh. (See Hilchot Tefillah 2:1.) and close the stores. 14b).On Mondays, the doors of the stores (Orach Chayim 575:4), the Ramah, and other commentaries, it appears that the leniencies mentioned here refer only to stores that sell food, but not those that carry other merchandise. are left slightly ajar towards evening and they may be opened [for business]. 1:6). On Thursdays, [the stores] may be opened the entire day [to allow people to purchase food] in honor of the Sabbath. If a store has two entrances, one entrance should be opened and the other closed.), it appears that this restriction applies on Mondays as well as on Thursdays. If the store has a display area in front of it, it may be opened in the normal manner on a Thursday without concern [for the above restriction]. 14b, explains that the display area prevents the entrances to the store from being seen. Hence, there is no difficulty in leaving them both open.

עָבְרוּ אֵלּוּ וְלֹא נַעֲנוּ. מְמַעֲטִין בְּמַשָּׂא וּמַתָּן וּבְבִנְיָן שֶׁל שִׂמְחָה כְּגוֹן צִיּוּר וְכִיּוּר. וּבִנְטִיעָה שֶׁל שִׂמְחָה כְּגוֹן מִינֵי הֲדַס וּמִינֵי אֲהָלִים. וּמְמַעֲטִין בְּאֵרוּסִין וְנִשּׂוּאִין אֶלָּא אִם כֵּן לֹא קִיֵּם מִצְוַת פְּרִיָּה וּרְבִיָּה. וְכָל מִי שֶׁקִּיֵּם מִצְוַת פְּרִיָּה וּרְבִיָּה אָסוּר לוֹ לְשַׁמֵּשׁ מִטָּתוֹ בִּשְׁנֵי רְעָבוֹן. וּמְמַעֲטִין בִּשְׁאֵלַת שָׁלוֹם בֵּין אָדָם לַחֲבֵרוֹ. וְתַּלְמִידֵי חֲכָמִים לֹא יִשְׁאֲלוּ שָׁלוֹם אֶלָּא כִּנְזוּפִין וּכִמְנֻדִּין לַמָּקוֹם. וְעַם הָאָרֶץ שֶׁנָּתַן לָהֶם שָׁלוֹם מַחְזִירִין לוֹ בְּשָׂפָה רָפָה וְכֹבֶד רֹאשׁ:

If these [fasts] pass without [their prayers] being answered, we should minimize our commercial activity,). Seemingly, the intent is that since the time is not favorable, it is unwise to invest money and effort in commercial endeavors (Kinat Eliyahu).There are, however, authorities who maintain that here also, the restriction involves only commercial activity associated with joy - e.g., preparing for a child's wedding or purchasing valuable articles, but ordinary business activities are permitted (Mishnah Berurah 575:18). construction projects associated with joy 1:7), the Rambam states that this refers to ornate buildings erected by the wealthy. There is, however, no restriction on ordinary building projects necessary for one's everyday purposes.The Shulchan Aruch (Orach Chayim 575:7) describes the prohibition as applying to "buildings of joy." The Mishnah Berurah 575:18 (based on the Tur) explains that this refers to all buildings that are unnecessary and are constructed for beauty and comfort. - e.g., those involving decorative patterns on the ceilings and walls, plantings associated with joy), the Rambam explains that this refers to spice and flower gardens planted for pleasure. One may, however, plant orchards for the purpose of growing fruit. There are no restrictions on such activity. - e.g., that of myrtle trees, and the erection of tents.We also minimize betrothals and marriages, (Orach Chayim 575) interprets this to mean that a person who has fulfilled the mitzvah of fathering children should not become betrothed or marry at all. unless one has not fulfilled the mitzvah of being fruitful and multiplying. 15:4.) Whoever has fulfilled this mitzvah is forbidden to engage in sexual relations in a year of famine. 11a derives this concept from Genesis 41:50, which states that Joseph's children were born before the famine. One can infer that during the famine he did not engage in relations.This restriction was instituted because it is proper to reduce our indulgence in pleasure in a time of communal distress.We also reduce the exchange of greetings, and the Torah sages should not exchange greetings at all. Rather, [they should conduct themselves as people] who have been rebuffed and ostracized by God. 14b states that it is proper to cover one's head with a cloak as mourners do. Nevertheless, neither the Rambam nor the Shulchan Aruch quotes this obligation (perhaps because even mourners did not generally observe this custom after the Talmudic era). When a common person greets them, they may return the greeting 14b); but when doing so, they should respond in a weak and concerned tone.

תַּלְמִידֵי חֲכָמִים חוֹזְרִין לְבַדָּם וּמִתְעַנִּים שֵׁנִי וַחֲמִישִׁי וְשֵׁנִי עַד שֶׁיֵּצֵא נִיסָן שֶׁל תְּקוּפָה אֲבָל לֹא הַצִּבּוּר. שֶׁאֵין גּוֹזְרִין עַל הַצִּבּוּר בִּשְׁבִיל גְּשָׁמִים שֶׁלֹּא יָרְדוּ יֶתֶר מִשְּׁלֹשׁ עֶשְׂרֵה תַּעֲנִיּוֹת אֵלּוּ. וּכְשֶׁמִּתְעַנִּין הַיְחִידִים עַד שֶׁיָּצָא נִיסָן מֻתָּרִין לֶאֱכל בַּלַּיְלָה וּמֻתָּרִין בַּעֲשִׂיַּת מְלָאכָה וּבִרְחִיצָה וּבְסִיכָה וְתַשְׁמִישׁ הַמִּטָּה וּנְעִילַת הַסַּנְדָּל כִּשְׁאָר כָּל הַתַּעֲנִיּוֹת. וּמַפְסִיקִין לְרָאשֵׁי חֳדָשִׁים וּפוּרִים. יָצָא נִיסָן שֶׁל תְּקוּפָה וְהוּא כְּשֶׁהִגִּיעַ הַשֶּׁמֶשׁ לִתְחִלַּת מַזַּל שׁוֹר אֵין מִתְעַנִּים. שֶׁאֵין הַגְּשָׁמִים בַּזְּמַן הַזֶּה אֶלָּא סִימַן קְלָלָה הוֹאִיל וְלֹא יָרְדוּ כָּל עִקָּר מִתְּחִלַּת הַשָּׁנָה:

The Torah scholars alone continue to fast, [beginning on the next] Monday, [and continuing on the following] Thursday and Monday - maintain that all cycles of fasts begin on Monday. Hence, if a cycle of fasts ends on Monday, the next cycle begins on the following Monday.This difference of opinion involves much more than one day, for these fasts are decreed in series of three. Thus, according to the opinion followed by the standard texts, the scholars would fast three days in every two weeks for the duration of the period. The other view, in contrast, would require them to fast on every Monday and Thursday. [in this manner] until the month of Nisan 1:7 states that these fasts should continue "until Nisan passes." In the Jerusalem Talmud's explanation of this Mishnah, it is explained that this refers to Nisan - as determined in relation to the spring season 9:3, the Rambam defines the beginning of spring as the time the sun enters the zodiac constellation of the goat. This is the beginning of April according to the secular calendar. - passes. This is not, however, required of the community. No more than these thirteen communal fasts are decreed because of a lack of rainfall. 14b considered thirteen fasts as the maximum a community should be required to undertake for this reason. More fasts would be considered an excessive burden. (Significantly, according to Kabbalah, the number thirteen is identified with God's attributes of mercy.)As mentioned in the commentary on Chapter 1, Halachah 4, this limit applies only regarding fasts decreed because of a lack of rain. When communal fasts are decreed because of other distressing circumstances, we should continue fasting until our prayers are answered.When these individuals fast until Nisan passes, they are allowed to eat at night and are allowed to perform work, to wash, to anoint themselves, to engage in sexual relations, and to wear shoes as on other fast days. They do not fast on Rashei Chodashim, nor on Purim.After the month of Nisan, as determined in relation to the spring season, passes - i.e., when the sun enters the sign of the bull - they should cease fasting. Since no rain has descended from the beginning of the year, rain in this season would be a sign of a curse.

בַּמֶּה דְּבָרִים אֲמוּרִים בְּאֶרֶץ יִשְׂרָאֵל וְכָל הַדּוֹמֶה לָהּ. אֲבָל מְקוֹמוֹת שֶׁעוֹנַת הַגְּשָׁמִים שֶׁלָּהֶן קֹדֶם י"ז בְּמַרְחֶשְׁוָן אוֹ אַחַר זְמַן זֶה כְּשֶׁיַּגִּיעַ זְמַנָּם וְלֹא יָרְדוּ גְּשָׁמִים יְחִידִים מִתְעַנִּים שֵׁנִי וַחֲמִישִׁי וְשֵׁנִי. וּמַפְסִיקִין בְּרָאשֵׁי חֳדָשִׁים וּבַחֲנֻכָּה וּבְפוּרִים. וְשׁוֹהִין אַחֲרֵי כֵן כְּמוֹ שִׁבְעָה יָמִים. אִם לֹא יָרְדוּ גְּשָׁמִים בֵּית דִּין גּוֹזְרִין עַל הַצִּבּוּר שְׁלֹשׁ עֶשְׂרֵה תַּעֲנִיּוֹת עַל הַסֵּדֶר שֶׁאָמַרְנוּ:

Where does the above apply? In Eretz Yisrael and in similar lands., the rainy season should begin at the start of Marcheshvan. In contrast, in places where the rainy season begins before or after the seventeenth of Marcheshvan, 575:24 states that this applies even if a country's rainy season begins after Shavuot. Note also Hilchot Tefillah 2:16-17, in which the Rambam discusses the question of requesting rain in lands other than Eretz Yisrael. This question is particularly relevant in regard to countries in the southern hemisphere. when the time [for the rains] arrives and no rain descends, individuals should [begin a series of three] fasts, [starting on] Monday [and continuing on the following] Thursday and Monday. They should not fast on Rashei Chodashim, Chanukah, or Purim.Afterwards, they should wait approximately seven days..) If rain does not descend, the court should decree thirteen communal fasts, according to the order described above.

כָּל תַּעֲנִיּוֹת שֶׁגּוֹזְרִין הַצִּבּוּר בְּחוּצָה לָאָרֶץ אוֹכְלִים בָּהֶם בַּלַּיְלָה וְדִינֵיהֶם כְּדִין שְׁאָר הַתַּעֲנִיּוֹת. שֶׁאֵין גּוֹזְרִין עַל הַצִּבּוּר תַּעֲנִית כְּגוֹן צוֹם כִּפּוּר אֶלָּא בְּאֶרֶץ יִשְׂרָאֵל בִּלְבַד וּבִגְלַל הַמָּטָר. וּבְאוֹתָן עֶשֶׂר תַּעֲנִיּוֹת שֶׁהֵן שָׁלֹשׁ אֶמְצָעִיּוֹת וְשֶׁבַע אַחֲרוֹנוֹת:

[The following laws apply to] all the communal fasts decreed in the diaspora: It is permitted to eat during the night, and they are governed by the same laws as other fasts. A communal fast resembling Yom Kippur is decreed only in Eretz Yisrael, 11b states, "There is no communal fast in Babylon other than Tish'ah B'Av" - i.e., in Babylon, there is no fast as severe as Yom Kippur, with the exception of Tish'ah B'Av. Significantly, Tosafot (loc. cit.) and Rashi (Pesachim 54b) explain that this refers to the land of Babylon, where rains were always plentiful and there was never a need for fasts.The Rambam - and other commentaries and authorities, including the Shulchan Aruch (Orach Chayim 575:10) - explain that the law which applies to Babylon, applies to the entire diaspora. It is not that there can be no need for a communal fast of this nature, but rather that, outside of Eretz Yisrael, the Jewish court lacks the authority to declare such a fast. (See the Jerusalem Talmud, Ta'anit 2:1.)The Ramban explains that the reason for the lack of authority is that there is no Nasi in the diaspora, and the declaration of a communal fast would require his approval. The Rashba states that the lack of authority stems from the lack of judges who have received the semichah (ordination) extending back in a chain to Moses. (See Hilchot Sanhedrin, Chapter 4.) According to these opinions, even in Eretz Yisrael today it is impossible to ordain communal fasts of this nature. Note the gloss of the Birkei Yosef on the Shulchan Aruch (Orach Chayim 575), where this concept is discussed and a rationale is given for fasting in Eretz Yisrael today.(Homiletically, it can be explained that the unity necessary to establish a community is possible only in Eretz Yisrael. In contrast, in the diaspora our greater involvement with material affairs prevents the establishment of true oneness among our people.) and only because of [a lack of] rain. This refers to the latter ten fasts - i.e., the middle series of three fasts and the final series of seven fasts.
