Leviticus 23:41-43

Holman Christian Standard Bible

⁴¹ You are to celebrate it as a festival to the Lord seven days each year. This is a permanent statute for you throughout your generations; you must celebrate it in the seventh month. ⁴² You are to live in booths^(A) for seven days. All the native-born of Israel must live in booths, ⁴³ so that your generations may know that I made the Israelites live in booths when I brought them out of the land of Egypt; I am Yahweh your God.”
