Leviticus 23:36-41

³⁶Seven 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.

³⁷These 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;

³⁸besides the sabbaths of Jehovah, and besides your gifts, and besides all your vows, and besides all your freewill-offerings, which ye give unto Jehovah.

³⁹Howbeit 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.

⁴⁰And 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.

⁴¹And 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.
