Leviticus 23:33-43

And Jehovah spake unto Moses, saying, Speak unto the children of Israel, saying, On the fifteenth day of this seventh month is the feast of tabernacles for seven days unto Jehovah. On the first day shall be a holy convocation: ye shall do no servile work. Seven days ye shall offer an offering made by fire unto Jehovah: on the eighth day shall be a holy convocation unto you; and ye shall offer an offering made by fire unto Jehovah: it is a solemn assembly; ye shall do no servile work. These are the set feasts of Jehovah, which ye shall proclaim to be holy convocations, to offer an offering made by fire unto Jehovah, a burnt-offering, and a meal-offering, a sacrifice, and drink-offerings, each on its own day; besides the sabbaths of Jehovah, and besides your gifts, and besides all your vows, and besides all your freewill-offerings, which ye give unto Jehovah. Howbeit on the fifteenth day of the seventh month, when ye have gathered in the fruits of the land, ye shall keep the feast of Jehovah seven days: on the first day shall be a solemn rest, and on the eighth day shall be a solemn rest. And ye shall take you on the first day the fruit of goodly trees, branches of palm-trees, and boughs of thick trees, and willows of the brook; and ye shall rejoice before Jehovah your God seven days. And ye shall keep it a feast unto Jehovah seven days in the year: it is a statute for ever throughout your generations; ye shall keep it in the seventh month. Ye shall dwell in booths seven days; all that are home-born in Israel shall dwell in booths; that 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 Jehovah your God.
