Leviticus 23:26-32

²⁶The Lord spoke to Moses, saying, ²⁷“On exactly the tenth day of this seventh month is the day of atonement; it shall be a holy convocation for you, and you shall humble your souls and present an offering by fire to the Lord. ²⁸You shall not do any work on this same day, for it is a day of atonement, to make atonement on your behalf before the Lord your God. ²⁹If there is any person who will not humble himself on this same day, he shall be cut off from his people. ³⁰As for any person who does any work on this same day, that person I will destroy from among his people. ³¹You shall do no work at all. It is to be a perpetual statute throughout your generations in all your dwelling places. ³²It is to be a sabbath of complete rest to you, and you shall humble your souls; on the ninth of the month at evening, from evening until evening you shall keep your sabbath.”
