סכות - “Speak to the people of Israel, saying, On the fifteenth day of this seventh month and for seven days is the Feast of Booths to the Lord... You shall dwell in booths for seven days. All native Israelites shall dwell in booths, that your generations may know that I made the people of Israel dwell in booths when I brought them out of the land of Egypt: I am the Lord your God.”
LEVITICUS 23:34, 42–43
