A sukkah which is higher than twenty cubits is disqualified; but Rebbi Jehudah qualifies it. “Rebbi Jehudah said, it happened that the sukkah of Helena (in Lydda) was higher than twenty cubits and the Sages were coming and going there and nobody was saying a word. They said to him, because she was a woman, and a woman is not obligated in sukkah. He said to them, is that proof? She had seven sons who were scholar students, And they all slept in it.

A sukkah which is more than twenty amot high is invalid; R. Yehudah, considers it kosher. R. Yehudah said, It once happened that the sukkah of Helen (in Lod) was higher than twenty amot, and the elders were going in and out of it, and no one said anything to her. [The sages] said to him, It was because she was a woman, and a woman is not obligated [to dwell] in a sukkah. He said to them, And did she not have seven sons who were scholars, and all were sleeping in the sukkah?

A sukkah that has more sun than shade is disqualified. For what case are we talking about? [In the event that the sun falls] from above, but if it falls from the sides, even if it is full of sun, it is qualified.

A sukkah where the sunshine is more than the shade is not valid. This applies only from above; but from the sides, even if they were wholly exposed to the sun, it is kosher. If one puts [schach] covering over the sides of a bed or the sides of a tree which are ten handbreadths high, if the part exposed to the sun be greater than that of the shade, it is kosher; but if not, it is invalid. The sukkah of shepherds, the sukkah of fruit-pickers, and a stolen sukkah, are invalid.
