Leviticus 23:41

³⁹And on the fifteenth day of this seventh month, when ye shall have completely gathered in the fruits of the earth, ye shall keep a feast to the Lord seven days; on the first day there shall be a rest, and on the eighth day a rest.

⁴⁰And on the first day ye shall take goodly fruit of trees, and branches of palm trees, and thick boughs of trees, and willows, and branches of osiers from the brook, to rejoice before the Lord your God seven days in the year.

— Leviticus 23:41 —

⁴²Seven days ye shall dwell in tabernacles: every native in Israel shall dwell in tents,

⁴³that your posterity may see, that I made the children of Israel to dwell in tents, when I brought them out of the land of Egypt: I am the Lord your God.
