Deuteronômio 16:13 Referências da Mishná: Mishnah Sukkah

A sukkah which is more than twenty cubits high is not valid. Rabbi Judah validates it. One which is not ten handbreadths high, or which does not have three walls, or which has more sun than shade, is not valid. An old sukkah: Bet Shammai invalidates it and Bet Hillel validates it. What is an “old sukkah”? Any one which he made thirty days before the festival; but if he made it for the purpose of the festival, even at the beginning of the year, it is valid.

If he trained a vine or a gourd or ivy over [the sukkah] and put skhakh on top of it, it is not valid. But if the skhakh is more than them, or if he cut them, it is valid. This is the general rule: whatever is susceptible to [ritual] impurity and does not grow from the ground may not be used for skhakh, but whatever is not susceptible to [ritual] impurity and does grow from ground soil may be used for skhakh.
