Sukkot, a holiday for the whole person (Torah in a Minute)
רַבִּי מָנֵי פָּתַח (תהלים לה, י): כָּל עַצְמֹתַי תֹּאמַרְנָה ה' מִי כָמוֹךָ, לֹא נֶאֱמַר פָּסוּק זֶה אֶלָּא בִּשְׁבִיל לוּלָב, הַשִּׁדְרָה שֶׁל לוּלָב דּוֹמָה לַשִּׁדְרָה שֶׁל אָדָם, וְהַהֲדַס דּוֹמֶה לָעַיִן, וַעֲרָבָה דּוֹמָה לַפֶּה, וְהָאֶתְרוֹג דּוֹמֶה לַלֵּב, אָמַר דָּוִד אֵין בְּכָל הָאֵיבָרִים גָּדוֹל מֵאֵלּוּ, שֶׁהֵן שְׁקוּלִין כְּנֶגֶד כָּל הַגּוּף, הֱוֵי: כָּל עַצְמוֹתַי תֹּאמַרְנָה.
Rabbi Mani opened, "'All of my bones shall say, "Lord, who is like you"' (Psalms 35:10). This verse was only stated for the sake of the lulav (the four species). The spine of the palm branch is similar to the spine of man. And the myrtle is similar to the eye. And the willow is similar to the mouth. And the etrog (citron), is similar to the heart. David said, 'In all of the limbs, there are no greater ones than these, as they are compared to the entire body.' This is [what is meant] by 'All of my bones shall say.'"
(מב) בַּסֻּכֹּ֥ת תֵּשְׁב֖וּ שִׁבְעַ֣ת יָמִ֑ים כָּל־הָֽאֶזְרָח֙ בְּיִשְׂרָאֵ֔ל יֵשְׁב֖וּ בַּסֻּכֹּֽת׃
(42) You shall live in booths seven days; all citizens in Israel shall live in booths,

(ז) מִי שֶׁהָיָה רֹאשׁוֹ וְרֻבּוֹ בַסֻּכָּה, וְשֻׁלְחָנוֹ בְתוֹךְ הַבַּיִת, בֵּית שַׁמַּאי פּוֹסְלִין, וּבֵית הִלֵּל מַכְשִׁירִין. אָמְרוּ לָהֶן בֵּית הִלֵּל לְבֵית שַׁמַּאי, לֹא כָךְ הָיָה מַעֲשֶׂה, שֶׁהָלְכוּ זִקְנֵי בֵית שַׁמַּאי וְזִקְנֵי בֵית הִלֵּל לְבַקֵּר אֶת רַבִּי יוֹחָנָן בֶּן הַחוֹרָנִי, וּמְצָאוּהוּ שֶׁהָיָה יוֹשֵׁב רֹאשׁוֹ וְרֻבּוֹ בַסֻּכָּה, וְשֻׁלְחָנוֹ בְתוֹךְ הַבַּיִת, וְלֹא אָמְרוּ לוֹ דָבָר. אָמְרוּ לָהֶן בֵּית שַׁמַּאי, מִשָּׁם רְאָיָה, אַף הֵם אָמְרוּ לוֹ, אִם כֵּן הָיִיתָ נוֹהֵג, לֹא קִיַּמְתָּ מִצְוַת סֻכָּה מִיָּמֶיךָ:

(7) If one's head and the majority of one's body is inside the sukkah, and one's table [upon which one is eating] is in the house, Beit Shamai invalidate it, and Beit Hillel validate it. [The scholars of] Beit Hillel said to [the scholars of] Beit Shamai, "Did it not happen that the elders of Beit Shamai and the elders of Beit Hillel went to visit Rabbi Yochanan ben Hachoroni, and they found him sitting with his head and the majority of his body inside the sukkah, while his table was in the house, and they did not say a thing to [stop] him." The [scholars of] Beit Shamai responded to them, "[Can one really bring] a proof from there?! They did in fact say to him, 'If such has been your custom, you have never fulfilled the mitzvah of sukkah in all your days!'"
