Leviticus 23:36-44

³⁶Seven days shall ye offer whole burnt offerings to the Lord, and the eighth day shall be a holy convocation to you; and ye shall offer whole burnt offerings to the Lord: it is a time of release, ye shall do no servile work.

³⁷These are the feasts to the Lord, which ye shall call holy convocations, to offer burnt offerings to the Lord, whole burnt offerings and their meat offerings, and their drink offerings, that for each day on its day:

³⁸besides the Sabbaths of the Lord, and besides your gifts, and besides all your vows, and besides your free will offerings, which ye shall give to the Lord.

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.

⁴¹It is a perpetual statute for your generations: in the seventh month ye shall keep it.

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.

⁴⁴And Moses recounted the feasts of the Lord to the children of Israel.
