The Gemara extols honoring Shabbat through eating three meals and says one who delights in Shabbat is given an unlimited inheritance. This is a major Talmudic basis for special food and drink in Shabbat preparation and enjoyment, and is commonly used to frame pre-Shabbat honoring practices.
רַב נַחְמָן בַּר יִצְחָק אָמַר: נִיצּוֹל מִשִּׁעְבּוּד גָּלִיּוֹת. כְּתִיב הָכָא: ״וְהִרְכַּבְתִּיךְ עַל בׇּמֳתֵי אָרֶץ״, וּכְתִיב הָתָם: ״וְאַתָּה עַל בָּמוֹתֵימוֹ תִדְרוֹךְ״. אָמַר רַב יְהוּדָה אָמַר רַב: כׇּל הַמְעַנֵּג אֶת הַשַּׁבָּת נוֹתְנִין לוֹ מִשְׁאֲלוֹת לִבּוֹ, שֶׁנֶּאֱמַר: ״וְהִתְעַנַּג עַל ה׳ וְיִתֶּן לְךָ מִשְׁאֲלוֹת לִבֶּךָ״. עוֹנֶג זֶה אֵינִי יוֹדֵעַ מַהוּ. כְּשֶׁהוּא אוֹמֵר ״וְקָרָאתָ לַשַּׁבָּת עוֹנֶג״ — הֱוֵי אוֹמֵר זֶה עוֹנֶג שַׁבָּת. בַּמֶּה מְעַנְּגוֹ? רַב יְהוּדָה בְּרֵיהּ דְּרַב שְׁמוּאֵל בַּר שִׁילַת מִשְּׁמֵיהּ דְּרַב אָמַר: בְּתַבְשִׁיל שֶׁל תְּרָדִין וְדָגִים גְּדוֹלִים וְרָאשֵׁי שׁוּמִין. רַב חִיָּיא בַּר אָשֵׁי אָמַר רַב: אֲפִילּוּ דָּבָר מוּעָט, וְלִכְבוֹד שַׁבָּת עֲשָׂאוֹ — הֲרֵי זֶה עוֹנֶג. מַאי הִיא? אָמַר רַב פָּפָּא: כָּסָא דְהַרְסָנָא. אָמַר רַבִּי יוֹסֵי: יְהֵא חֶלְקִי מֵאוֹכְלֵי שָׁלֹשׁ סְעוּדוֹת בַּשַּׁבָּת. אָמַר רַבִּי יוֹסֵי: יְהֵא חֶלְקִי מִגּוֹמְרֵי הַלֵּל בְּכׇל יוֹם. אִינִי?! וְהָאָמַר מָר: הַקּוֹרֵא הַלֵּל בְּכׇל יוֹם הֲרֵי זֶה מְחָרֵף וּמְגַדֵּף! כִּי קָאָמְרִינַן — בִּפְסוּקֵי דְזִמְרָא.
Rav Naḥman bar Yitzḥak said: One who delights in Shabbat is rescued from the oppression of exile. He derives it by means of a verbal analogy. It is written here, with regard to Shabbat: “And I will cause you to ride on the heights [bamotei] of the world” (Isaiah 58:14), and it is written there: “You are fortunate Israel, who is like you? A nation redeemed by God, the shield that aids you and the sword of your triumph. Your enemies will try to defeat you and you will trample their high places [bamoteimo]” (Deuteronomy 33:29). Rav Yehuda said that Rav said: With regard to anyone who delights in the Shabbat, God grants him his heart’s desires, as it is stated: “And you shall delight in God and He will grant you your heart’s desires” (Psalms 37:4). This delight in God, which is mentioned in the verse, I do not know what it is. When it says: “And you shall call the Shabbat delight,” one must say: It is the delight of Shabbat. The Gemara asks: With what does one delight in the day of Shabbat? Rav Yehuda, son of Rav Shmuel bar Sheilat, said in the name of Rav: With a dish of beets, and large fish, and heads of garlic. Rav Ḥiyya bar Ashi said that Rav said: Even with regard to a small item and one prepared it in deference to Shabbat, it is a delight. The Gemara asks: What is the small item mentioned? Rav Pappa said: Small fried fish. Rabbi Yosei said: May my portion be among those who eat three meals on Shabbat. Apropos this statement of Rabbi Yosei, the Gemara cites additional declarations. Rabbi Yosei said: May my portion be among those who complete hallel every day. The Gemara is surprised at this: Is that so? Didn’t the Master say: One who reads hallel every day is tantamount to one who curses and blasphemes God. He displays contempt for hallel by not reserving it for days on which miracles occurred. The Gemara answers: When we say this statement of Rabbi Yosei, we are referring to the verses of praise [pesukei dezimra], recited during the morning service, not to hallel (Psalms 113–118) recited on special days.
