Leviticus 23:23-35

Then the LORD spoke to Moses, saying, “Speak to the children of Israel, saying: ‘In the seventh month, on the first day of the month, you shall have a sabbath-rest, a memorial of blowing of trumpets, a holy convocation. You shall do no customary work on it; and you shall offer an offering made by fire to the LORD.’ ” And the LORD spoke to Moses, saying: “Also the tenth day of this seventh month shall be the Day of Atonement. It shall be a holy convocation for you; you shall afflict your souls, and offer an offering made by fire to the LORD. And you shall do no work on that same day, for it is the Day of Atonement, to make atonement for you before the LORD your God. For any person who is not afflicted in soul on that same day shall be cut off from his people. And any person who does any work on that same day, that person I will destroy from among his people. You shall do no manner of work; it shall be a statute forever throughout your generations in all your dwellings. It shall be to you a sabbath of solemn rest, and you shall afflict your souls; on the ninth day of the month at evening, from evening to evening, you shall celebrate your sabbath.” Then the LORD spoke to Moses, saying, “Speak 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. On the first day there shall be a holy convocation. You shall do no customary work on it.
