Leviticus 23:42-44

New Catholic Bible

⁴² You shall dwell in tents for seven days. All native-born Israelites shall dwell in tents ⁴³ so that all of your generations may know that I made the children of Israel dwell in tents when I brought them out of the land of Egypt. I am the Lord, your God.”

⁴⁴ This is how Moses described the feasts of the Lord to the children of Israel.
