Leviticus 23:29-39

²⁹Every soul that shall not be humbled in that day, shall be cut off from among its people.

³⁰And every soul which shall do work on that day, that soul shall be destroyed from among its people.

³¹Ye shall do no manner of work: it is a perpetual statute throughout your generations in all your habitations.

³²It shall be a holy Sabbath to you; and ye shall humble your souls, from the ninth day of the month: from evening to evening ye shall keep your Sabbaths.

³³And the Lord spoke to Moses, saying,

³⁴Speak to the children of Israel, saying, On the fifteenth day of this seventh month, there shall be a feast of tabernacles seven days to the Lord.

³⁵And on the first day shall be a holy convocation; ye shall do no servile work.

³⁶Seven days shall ye offer whole burnt offerings to the Lord, and the eighth day shall be a holy convocation to you; and ye shall offer whole burnt offerings to the Lord: it is a time of release, ye shall do no servile work.

³⁷These are the feasts to the Lord, which ye shall call holy convocations, to offer burnt offerings to the Lord, whole burnt offerings and their meat offerings, and their drink offerings, that for each day on its day:

³⁸besides the Sabbaths of the Lord, and besides your gifts, and besides all your vows, and besides your free will offerings, which ye shall give to the Lord.

³⁹And on the fifteenth day of this seventh month, when ye shall have completely gathered in the fruits of the earth, ye shall keep a feast to the Lord seven days; on the first day there shall be a rest, and on the eighth day a rest.
