וְתִיפּוֹק לֵיהּ דְּהָוֵה לֵיהּ יוֹם שֶׁנֶּהֱרַג בּוֹ גְּדַלְיָה בֶּן אֲחִיקָם אָמַר רַב לֹא נִצְרְכָה אֶלָּא לֶאֱסוֹר אֶת שֶׁלְּפָנָיו The Gemara raises a difficulty: But if this was at the time that the Temple was standing, derive the prohibition against fasting on the third of Tishrei from the fact that it is the day that Gedaliah, son of Ahikam, was killed. During the time of the Temple the biblical fast days were celebrated as days of joy. Rav said: It was only necessary to include the third of Tishrei in Megillat Ta’anit in order to prohibit fasting on the preceding day as well. Fasting was forbidden not only on the actual days listed in Megillat Ta’anit, but also on the preceding day and the following day.
שֶׁלְּפָנָיו נָמֵי תִּיפּוֹק לֵיהּ דְּהָוֵה לֵיהּ יוֹם שֶׁלְּאַחַר רֹאשׁ חֹדֶשׁ רֹאשׁ חֹדֶשׁ דְּאוֹרָיְיתָא וּדְאוֹרָיְיתָא לָא בָּעֵי חִיזּוּק The Gemara raises another difficulty: With regard to the prohibition against fasting on the preceding day, the second of Tishrei, also derive it because it is the day after the New Moon, and fasting is forbidden not only on festive days, but also on the preceding day and the following day. The Gemara rejects this argument: The New Moon is by Torah law, and festive days that are by Torah law do not require reinforcement. Therefore no decree was ever enacted prohibiting fasting on the days before and after.
דְּתַנְיָא הַיָּמִים הָאֵלֶּה הַכְּתוּבִין בִּמְגִילַּת תַּעֲנִית אֲסוּרִין בֵּין לִפְנֵיהֶם בֵּין לְאַחֲרֵיהֶם שַׁבָּתוֹת וְיָמִים טוֹבִים הֵם אֲסוּרִים לִפְנֵיהֶן וּלְאַחֲרֵיהֶן מוּתָּרִין מָה הֶפְרֵשׁ בֵּין זֶה לָזֶה הַלָּלוּ דִּבְרֵי תוֹרָה וְאֵין דִּבְרֵי תוֹרָה צְרִיכִין חִיזּוּק הַלָּלוּ דִּבְרֵי סוֹפְרִים וְדִבְרֵי סוֹפְרִים צְרִיכִין חִיזּוּק As it is taught in a baraita: These days that are written in Megillat Ta’anit are days on which fasting is prohibited, as are both the day before them and the day after them. With regard to Shabbatot and Festivals, fasting on them is forbidden, but on the day before them and the day after them fasting is permitted. What is the difference between this class of days and that class of days? These days, Shabbatot and Festivals, are by Torah law, and Torah laws do not need reinforcement, and therefore even if a fast day were decreed on the day before or after them, the Festival itself would not be nullified; whereas those days mentioned in Megillat Ta’anit are by rabbinic law, and rabbinic laws need reinforcement, and therefore fasting is prohibited even on the day before and the day after.
וְתִיפּוֹק לֵיהּ דְּהָוֵה לֵיהּ יוֹם שֶׁלִּפְנֵי יוֹם שֶׁנֶּהֱרַג בּוֹ גְּדַלְיָה בֶּן אֲחִיקָם אָמַר רַב אָשֵׁי גְּדַלְיָה בֶּן אֲחִיקָם דִּבְרֵי קַבָּלָה הוּא וְדִבְרֵי קַבָּלָה כְּדִבְרֵי תוֹרָה דָּמוּ The Gemara raises yet another difficulty: The prohibition against fasting on the second of Tishrei, derive it from the fact that it is the day before the day that Gedaliah, son of Ahikam, was killed, and since in Temple times the fast of Gedaliah was celebrated as a festive day, fasting should also be prohibited on the preceding day. Rav Ashi said: The fast of Gedaliah, son of Ahikam, is derived from the texts of the tradition, i.e., Prophets and Writings, and as the texts of the tradition are treated like Torah statements for this purpose, they too do not need reinforcement.

And this is explained: For the wicked kingdom issued a decree against Israel that they should not occupy themselves with Torah study, and that they should not circumcise their sons, and that they should desecrate Shabbat. What did Yehuda ben Shammua and his colleagues do? They went and took advice from a certain matron [matronita] whom all the prominent men of Rome would visit regularly, thinking that she would know how to annul the decree.
אָמְרָה לָהֶם בּוֹאוּ וְהַפְגִּינוּ בַּלַּיְלָה הָלְכוּ וְהִפְגִּינוּ בַּלַּיְלָה אָמְרוּ אֵי שָׁמַיִם לֹא אֲחֵיכֶם אֲנַחְנוּ וְלֹא בְּנֵי אָב אֶחָד אֲנַחְנוּ וְלֹא בְּנֵי אֵם אַחַת אֲנַחְנוּ מָה נִשְׁתַּנֵּינוּ מִכׇּל אוּמָּה וְלָשׁוֹן שֶׁאַתֶּם גּוֹזְרִין עָלֵינוּ גְּזֵירוֹת קָשׁוֹת וּבִיטְּלוּם וְאוֹתוֹ הַיּוֹם עֲשָׂאוּהוּ יוֹם טוֹב וְאִי סָלְקָא דַּעְתָּךְ בָּטְלָה מְגִילַּת תַּעֲנִית קַמָּיָיתָא בְּטוּל אַחְרָנְיָיתָא מוֹסִיפִין She said to them as follows: Come and cry out [hafgginu] at night in the streets and markets. They went and cried out at night, saying: O Heavens! Are we Jews not your brothers; are we not children of one father; are we not children of one mother? How are we different from every other nation and tongue that you issue such harsh decrees against us? And indeed the decrees were annulled, and the Sages made that day a festive day. And if it enters your mind to say that Megillat Ta’anit has been nullified, can you say that the first prohibitions against fasting they annulled, and then later ones were added?

And proof that Rabbi Yehuda ben Shammua was a student of Rabbi Meir may be brought, as we learned in a mishna: With regard to glass vessels that had holes in them, which afterward were filled in with lead, the Sages dispute whether the utensil is considered a whole utensil, which can become ritually impure, or whether it is considered a broken utensil, which does not. Rabban Shimon ben Gamliel said: Yehuda ben Shammua declares that it becomes impure, in the name of Rabbi Meir;
