Sukkah 23

The Gemara states that Rabbi Yehudah maintains that it is said the festival of Sukkos you shall make for yourself for seven days. This means that a Sukkah that is fit for seven days is considered a valid Sukkah, but a Sukkah that is not fit for all seven days of Sukkos is not considered to be a valid Sukkah. It is noteworthy that it is said on that day I will raise up the fallen booth (Sukkah) of Dovid. Furthermore, it is said for though the righteous one may fall seven times, he will arise. These two verses can be interpreted homiletically to mean that although the Sukkah, i.e. the righteous one, may fall seven times, in the future everyone will see that the fall of the righteous was not a true downfall. Rather, the fact that the righteous occasionally fall is a sign that they will be raised up in the future. This is alluded to in the verse regarding the construction of a Sukkah. One must build a Sukkah that is fit for seven days, i.e. one should be prepared to fall at certain times in life, but in the future HaShem will raise up the booth of Dovid, i.e. the righteous.
