Leviticus 23:36-43

³⁶Seven days ye shall offer an offering made by fire to the LORD: on the eighth day shall be a holy convocation to you, and ye shall offer an offering made by fire to the LORD: it is a solemn assembly; and ye shall do no servile work in it .

³⁷These are the feasts of the LORD, which ye shall proclaim to be holy convocations, to offer an offering made by fire to the LORD, a burnt-offering, and a meat-offering, a sacrifice, and drink-offerings, every thing upon its day:

³⁸Beside the sabbaths of the LORD, and beside your gifts, and beside all your vows, and beside all your free-will-offerings, which ye give to the LORD.

³⁹Also in the fifteenth day of the seventh month, when ye have gathered in the fruit of the land, ye shall keep a feast to the LORD seven days: on the first day shall be a sabbath, and on the eighth day shall be a sabbath.

⁴⁰And ye shall take you on the first day the boughs of goodly trees, branches of palm-trees, and the boughs of thick trees, and willows of the brook; and ye shall rejoice before the LORD your God seven days.

⁴¹And ye shall keep it a feast to the LORD seven days in the year. It shall be a statute for ever in your generations; ye shall celebrate it in the seventh month.

⁴²Ye shall dwell in booths seven days: all that are Israelites born shall dwell in booths:

⁴³That your generations may know that I made the children of Israel to dwell in booths, when I brought them out of the land of Egypt: I am the LORD your God.
