Leviticus 23:22-32

22"And when you reap the harvest of your land, you shall not reap your field right up to its edge, nor shall you gather the gleanings after your harvest. You shall leave them for the poor and for the sojourner: I am the Lord your God."

23And the Lord spoke to Moses, saying,

24"Speak to the people of Israel, saying, In the seventh month, on the first day of the month, you shall observe a day of solemn rest, a memorial proclaimed with blast of trumpets, a holy convocation.

25You shall not do any ordinary work, and you shall present a food offering to the Lord."

26And the Lord spoke to Moses, saying,

27"Now on 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 yourselves and present a food offering to the Lord.

28And 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.

29For whoever is not afflicted on that very day shall be cut off from his people.

30And whoever does any work on that very day, that person I will destroy from among his people.

31You shall not do any work. It is a statute forever throughout your generations in all your dwelling places.

32It 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."
