On the first night of Sukkos there is a chiyuv to eat in the sukkah that no other night of the Yom Tov carries, learned from leil Pesach through the gezeirah shava of tes vav tes vav. The rishonim argue over what that limud brings along with it: the shiur, the zman, and whether it holds even when the rain is coming down. And when it does rain, a family and guests are sitting at the table waiting to eat.

In this episode:

- K'zayis or yoser mi'k'beitza, and why the Mishnah Berurah wants us to be choshesh for the other rishonim

- Whether lechem oni, matzaschem and the zman of chatzos carry over from matzah to the sukkah, and whether honey on the challah is a problem

- Why the Rema says not to eat from chatzos on Erev Sukkos, earlier than Erev Pesach

- Rain on leil rishon: kiddush in the sukkah, shehecheyanu without leishev, and how long to wait for the rain to stop

- The Sha'ar HaTziyun on guests and aniyim, and the issur of ba'al te'acher

- Why Parshas Emor and Parshas Pinchas list sukkah and the daled minim only after closing the moadim
