23 And the Lord spoke to Moses, saying, 24 “Speak to the people of Israel, saying, In lthe seventh month, on the first day of the month, you shall observe a day of solemn rest, ma memorial proclaimed with blast of trumpets, a holy convocation. 25 You shall not do any ordinary work, and you shall present a food offering to the Lord.”
26 And the Lord spoke to Moses, saying, 27 “Now non the tenth day of this seventh month is the Day of Atonement. It shall be for you a time of holy convocation, and you shall afflict yourselves4 and present a food offering to the Lord. 28 And you shall not do any work on that very day, for it is a Day of Atonement, to make atonement for you before the Lord your God. 29 For whoever is not afflicted5 on that very day oshall be cut off from his people. 30 And whoever does any work on that very day, that person I will destroy from among his people. 31 You shall not do any work. It is a statute forever throughout your generations in all your dwelling places. 32 It shall be to you a Sabbath of solemn rest, and you shall afflict yourselves. On the ninth day of the month beginning at evening, from evening to evening shall you keep your Sabbath.”
