night of the Festival. The Sages of the Mishnah, however, taught that there is no making up for this, and of this Ecclesiastes said: "That which is crooked cannot be made straight, and that which is wanting cannot be numbered." The Gemara explained that Rabbi Eliezer said that one needs to eat 14 meals because the words of , "You shall dwell," imply that one should dwell just as one normally dwells. And so, just as in a normal dwelling, one has one meal by day and one by night, so in the sukkah, one should have one meal by day and one by night. And the Gemara explained that the Sages taught that , "You shall dwell," implies that just as in one's dwelling, one eats if one wishes, and does not eat if one does not wish, so also with a sukkah one eats only if one wishes. But if so, the Gemara asked, why is the meal on the first night mandatory? Rabbi Johanan answered in the name of Rabbi Simeon ben Jehozadak that with regard to Sukkot, says "the fifteenth," just as says "the fifteenth" with regard to Passover (implying similarity in the laws for the two Festivals). And for Passover, says, "At evening you shall eat unleavened bread," indicating that only the first night is obligatory (to eat unleavened bread). So also for Sukkot, the only first night is also obligatory (to eat in the sukkah). The Gemara then reported that Bira said in the name of Rabbi Ammi that Rabbi Eliezer recanted his statement that one is obliged to eat 14 meals in the sukkah, and changed his position to agree with the Sages. The Gemara taught that a desert later in the holiday may be regarded as a compensating meal to fulfill one's obligation to eat the first meal. Rabbi Joshua maintained that rejoicing on a Festival is a religious duty. For it was taught in a Baraita: Rabbi Eliezer said: A person has nothing else to do on a Festival aside from either eating and drinking or sitting and studying. Rabbi Joshua said: Divide it: Devote half of the Festival to eating and drinking, and half to the House of Study. Rabbi Johanan said: Both deduce this from the same verse. One verse says, "a solemn assembly to the Lord your God," while says, "there shall be a solemn assembly to you."
