Leviticus 23:29-39

²⁹For whatsoever soul it be that shall not be afflicted in that same day; he shall be cut off from his people.

³⁰And whatsoever soul it be that doeth any manner of work in that same day, that soul will I destroy from among his people.

³¹Ye shall do no manner of work: it is a statute for ever throughout your generations in all your dwellings.

³²It shall be unto you a sabbath of solemn rest, and ye shall afflict your souls: in the ninth day of the month at even, from even unto even, shall ye keep your sabbath.

³³And Jehovah 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 Jehovah.

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

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.
