Leviticus 23:41-43

41You are to celebrate it as a festival to Adonai for seven days in the year. It is a statute forever throughout your generations—you are to celebrate it in the seventh month.

42You are to live in sukkot for seven days. All the native-born in Israel are to live in sukkot,

43so that your generations may know that I had Bnei-Yisrael to dwell in sukkot when I brought them out of the land of Egypt. I am Adonai your God.”
