The verse “And Moses declared to the children of Israel the appointed seasons of the Lord” (Leviticus 23:44) indicates that part of the mitzva of the Festivals is that they should read the portion relating to them, each one in its appointed time. The Sages taught in a baraita: Moses enacted for the Jewish people that they should make halakhic inquiries and expound upon the matter of the day. They should occupy themselves with the halakhot of Passover on Passover, with the halakhot of Shavuot on Shavuot, and with the halakhot of Sukkot on Sukkot.
(א) וַיְהִ֗י בִּימֵי֙ שְׁפֹ֣ט הַשֹּׁפְטִ֔ים וַיְהִ֥י רָעָ֖ב בָּאָ֑רֶץ וַיֵּ֨לֶךְ אִ֜ישׁ מִבֵּ֧ית לֶ֣חֶם יְהוּדָ֗ה לָגוּר֙ בִּשְׂדֵ֣י מוֹאָ֔ב ה֥וּא וְאִשְׁתּ֖וֹ וּשְׁנֵ֥י בָנָֽיו׃
(1) In the days when the judges judged, there was a famine in the land; and a man of Bethlehem in Judah, with his wife and two sons, went to reside in the country of Moab.
וא"ר יוחנן מאי דכתיב (רות א, א) ויהי בימי שפוט השופטים דור ששופט את שופטיו אומר לו טול קיסם מבין (עיניך) אומר לו טול קורה מבין עיניך אמר לו (ישעיהו א, כב)
And further, with regard to Rabbi Elazar’s statement in the baraita that the generation of the judging of the Judges was one of vanity, Rabbi Yoḥanan says: What is the meaning of that which is written: “And it happened in the days of the judging of the Judges” (Ruth 1:1)? This indicates a generation that judged its judges. If a judge would say to the defendant standing before him: Remove the splinter from between your eyes, meaning rid yourself of some minor infraction, the defendant would say to him: Remove the beam from between your eyes, meaning you have committed far more severe sins.
(ב) בְּאַרְבָּעָה פְרָקִים הָעוֹלָם נִדּוֹן, בְּפֶסַח עַל הַתְּבוּאָה, בַּעֲצֶרֶת עַל פֵּרוֹת הָאִילָן, בְּרֹאשׁ הַשָּׁנָה כָּל בָּאֵי הָעוֹלָם עוֹבְרִין לְפָנָיו כִּבְנֵי מָרוֹן, שֶׁנֶּאֱמַר (תהלים לג) הַיּוֹצֵר יַחַד לִבָּם, הַמֵּבִין אֶל כָּל מַעֲשֵׂיהֶם. וּבֶחָג נִדּוֹנִין עַל הַמָּיִם:
(2) At four times the world is judged: On Pesach, for the crops. On Shavuot, for the fruits of the tree. On Rosh Hashnah, all the world passes before Him like sheep, as it says, "He that fashioneth the hearts of them all, that considereth all their doings." (Psalms 33:15) And on Sukkot, they are judged for the water.
(שם)
מַה כְּתִיב אַחֲרָיו שָׁלֹש רְגָלִים תָּחֹג לִי בַּשָּׁנָה, קָבַע לָהֶן הַקָּדוֹשׁ בָּרוּךְ הוּא לְיִשְׂרָאֵל... וְחַג הַקָּצִיר, שֶׁבּוֹ נָתַן לָהֶם אֶת הַתּוֹרָה שֶׁאוֹכְלִין מִפֵּרוֹתֶיהָ בָּעוֹלָם הַזֶּה וְהַקֶּרֶן קַיֶּמֶת לָהֶן לָעוֹלָם הַבָּא, שֶׁנֶּאֱמַר: טוֹב פִּרְיִי מֵחָרוּץ וּמִפָּז וּתְבוּאָתִי מִכֶּסֶף נִבְחָר (משלי ח, יט).
What is written following this? Three times thou shalt keep a festival unto Me in the year (ibid., v. 14). The harvest festival (Shavuot), on which He gave them the Torah, the fruits of which they were to enjoy in this world and their interest in the world-to-come, as it is said: My fruit is better than gold, yea, than fine gold; and My produce than choice silver (Prov. 8:19);
מר בריה דרבינא כולה שתא הוה יתיב בתעניתא לבר מעצרתא ופוריא ומעלי יומא דכיפורי עצרת יום שניתנה בו תורה פוריא ימי משתה ושמחה...
The Gemara relates: Mar, son of Ravina, would spend the entire year fasting during the day and eating only sparsely at night, except for Shavuot, Purim, and the eve of Yom Kippur. He made these exceptions for the following reasons: Shavuot because it is the day on which the Torah was given and there is a mitzva to demonstrate one’s joy on that day...
ן בְּגָדִים וְתַכְשִׁיטִין נָאִים כְּפִי מָמוֹנוֹ. וְהָאֲנָשִׁים אוֹכְלִין בָּשָׂר וְשׁוֹתִין יַיִן שֶׁאֵין שִׂמְחָה אֶלָּא בְּבָשָׂר וְאֵין שִׂמְחָה אֶלָּא בְּיַיִן...
(18) The children, for example, should be given parched grain, nuts, and sweetmeats; the womenfolk should be presented with pretty clothes and trinkets according to one's means; the menfolk should eat meat and drink wine, for there is no real rejoicing without the use of meat and wine...
(יח) ... וּכְשֶׁהוּא אוֹכֵל וְשׁוֹתֶה חַיָּב לְהַאֲכִיל לַגֵּר לַיָּתוֹם וְלָאַלְמָנָה עִם שְׁאָר הָעֲנִיִּים הָאֻמְלָלִים. אֲבָל מִי שֶׁנּוֹעֵל דַּלְתוֹת חֲצֵרוֹ וְאוֹכֵל וְשׁוֹתֶה הוּא וּבָנָיו וְאִשְׁתּוֹ וְאֵינוֹ מַאֲכִיל וּמַשְׁקֶה לַעֲנִיִּים וּלְמָרֵי נֶפֶשׁ אֵין זוֹ שִׂמְחַת מִצְוָה אֶלָּא שִׂמְחַת כְּרֵסוֹ. וְעַל אֵלּוּ נֶאֱמַר (הושע ט ד) "זִבְחֵיהֶם כְּלֶחֶם אוֹנִים לָהֶם כָּל אֹכְלָיו יִטַּמָּאוּ כִּי לַחְמָם לְנַפְשָׁם". וְשִׂמְחָה כָּזוֹ קָלוֹן הִיא לָהֶם שֶׁנֶּאֱמַר (מלאכי ב ג) "וְזֵרִיתִי פֶרֶשׁ עַל פְּנֵיכֶם פֶּרֶשׁ חַגֵּיכֶם":
(18) ... Anyone, however, who locks the doors of his courtyard and eats and drinks along with his wife and children, without giving anything to eat and drink to the poor and the desperate, does not observe a religious celebration but indulges in the celebration of his stomach.— —
