Leviticus 23:41-43

41You shall thus celebrate it as a feast to the Lord for seven days in the year. It shall be a perpetual statute throughout your generations; you shall celebrate it in the seventh month.

42You shall 1live 2in booths for seven days; all the native-born in Israel shall 3live in booths,

43so that 4your generations may know that I had the sons of Israel live in booths when I brought them out from the land of Egypt. I am the Lord your God.’”
