Leviticus 23:41-43

New Revised Standard Version Catholic Edition

⁴¹ You shall keep it as a festival to the Lord seven days in the year; you shall keep it in the seventh month as a statute forever throughout your generations. ⁴² You shall live in booths for seven days; all that are citizens in Israel shall live in booths, ⁴³ so that your generations may know that I made the people of Israel live in booths when I brought them out of the land of Egypt: I am the Lord your God.
