115 Sukkah 2/9 & 3/1-3

(9) During the whole seven days [of the festival] one makes his sukkah [his] permanent [dwelling], and his house [a] temporary [dwelling]. If rains fell, starting when is one permitted to clear out [of the sukkah]? When a stiff dish [of food] would be spoiled. They [the elders] illustrate this with a parable: To what can this matter be compared? To a slave who came to pour a goblet for his master, and he [the master] poured a bowl-full [of water] in his face.

(1) A lulav [a palm branch, one of the four species which it is a mitzvah to take on Sukkot] which was stolen or dried out is invalid. One which comes from an ashera [a tree dedicated to idolatry], or from a condemned city [an idolatrous city which must be destroyed] is invalid. If its tip was snapped off, or its leaves missing, it is invalid; if its leaves were [merely] separated, it is valid. Rabbi Yehudah says: One must bind it together from the top [in order for it to be valid]. The palms of Iron Mount are valid [for use as a lulav]. A lulav that has three hand-breadths [in length] by which to shake it, is valid.

(2) A myrtle branch which was stolen or dried out is invalid [for use in the mitzvah of the four species]. One which comes from an ashera, or from a condemned city is invalid. If its tip was snapped off, or its leaves missing, or if its berries are more numerous than its leaves, it is invalid; and if one decreased them [the berries], it is valid. And one may not decrease them on the festival.

(3) A willow branch which was stolen is dried out is invalid [for use in the mitzvah of the four species]. One which comes from an ashera, or from a condemned city, is invalid. If its tip was snapped off, or its leaves missing, or if it is a Euphrates poplar‎, it is invalid. One that is withered, or that a few of its leaves have fallen, or that grew in a naturally watered area, is valid.
