Leviticus 23:33-39

33And the LORD spake unto Moses, saying,

34Speak unto the children of Israel, saying, On the fifteenth day of this seventh month is the feast of tabernacles for seven days unto the LORD.

35On the first day shall be an holy convocation: ye shall do no servile work.

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

37These are the set feasts of the LORD, which ye shall proclaim to be holy convocations, to offer an offering made by fire unto the LORD, a burnt offering, and a meal offering, a sacrifice, and drink offerings, each on its own day:

38beside the sabbaths of the LORD, and beside your gifts, and beside all your vows, and beside all your freewill offerings, which ye give unto the LORD.

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 the LORD seven days: on the first day shall be a solemn rest, and on the eighth day shall be a solemn rest.
