Lev 23:26-32

The Day of Atonement 26The Lord spoke to Moses, saying:27Now, the tenth day of this seventh month is the day of atonement; it shall be a holy convocation for you: you shall deny yourselves and present the Lord's offering by fire;28and you shall do no work during that entire day; for it is a day of atonement, to make atonement on your behalf before the Lord your God.29For anyone who does not practice self-denial during that entire day shall be cut off from the people.30And anyone who does any work during that entire day, such a one I will destroy from the midst of the people.31You shall do no work: it is a statute forever throughout your generations in all your settlements.32It shall be to you a sabbath of complete rest, and you shall deny yourselves; on the ninth day of the month at evening, from evening to evening you shall keep your sabbath.
