Leviticus 23:29-39

²⁹For whatever soul it may be that shall not be afflicted in that same day, he shall be cut off from among his people.

³⁰And whatever soul it may be that doeth any work in that same day, the same soul will I destroy from among his people.

³¹Ye shall do no manner of work. It shall be a statute for ever throughout your generations in all your dwellings.

³²It shall be to you a sabbath of rest, and ye shall afflict your souls in the ninth day of the month at evening: from evening to evening shall ye celebrate your sabbath.

³³And the LORD spoke to Moses, saying,

³⁴Speak to the children of Israel, saying, The fifteenth day of this seventh month shall be the feast of tabernacles for seven days to the LORD.

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

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.
