Sukkah 43B

״תשבו״ ״תשבו״⁠ — לגזרה שוה. נאמר כאן ״תשבו״, ונאמר במלואים ״תשבו״. מה להלן ⁠— ״ימים״ ואפילו לילות, אף כאן ⁠— ״ימים״ ואפילו לילות.

“You should reside,” “you should reside,” by means of a verbal analogy. It is stated here, with regard to sukka: “You should reside in sukkot 7 days” (Leviticus 23:42), and it is stated with regard to the inauguration of the Tabernacle: “And at the door of the Tent of Meeting you should reside day and night 7 days” (Leviticus 8:35). Just as there, with regard to the inauguration, the meaning is days and even nights, so too here, with regard to sukka, the meaning is days and even nights.

ערבה שבעה. כיצד? ערבה בשביעי מאי טעמא דחיא שבת? אמר רבי יוחנן: כדי לפרסמה שהיא מן התורה. אי הכי, לולב נמי לידחי, כדי לפרסמו שהוא מן התורה!

§ The Mishnah continues: The altar is encircled with the willow branch for 7 days. How so? If the 7th day of performing the mitzva of the willow branch occurs on Shabbat, since on that day the mitzva of the willow branch is a mitzva by Torah law, it overrides Shabbat and the mitzva of the willow branch is then performed 7 days. The Talmud asks: With regard to the mitzva of the willow branch on the 7th day, what is the reason that it overrides Shabbat? R' Yoḥanan said: It is in order to publicize that it is a mitzva that applies by Torah law, since it is not written explicitly in the Torah. The Talmud raises an objection: If so, lulav too should override Shabbat in the Temple on the other days of Sukkot as well and not only on the 1st day in order to publicize that it is a mitzva by Torah law all 7 days, since that too is not written explicitly in the Torah.
