Leviticus 23:39-43

Amplified Bible

³⁹ ‘On exactly the fifteenth day of the seventh month (nearly October), when you have gathered in the crops of the land, you shall celebrate the feast of the Lord for seven days, with a Sabbath rest on the first day and a Sabbath rest on the eighth day. ⁴⁰ Now on the first day you shall take for yourselves the foliage of beautiful trees, branches of palm trees, and boughs of thick (leafy) trees, and willows of the brook [and make booths of them]; and you shall rejoice before the Lord your God for seven days. ⁴¹ You shall celebrate it as a feast to the Lord for seven days in the year. It shall be a permanent statute throughout your generations; you shall celebrate it in the seventh month. ⁴² You shall live in booths (temporary shelters) for seven days; all native-born in Israel shall live in booths, ⁴³ so that your generations may know that I had the sons of Israel live in booths when I brought them out of the land of Egypt. I am the Lord your God.’”
