Leviticus 23:22-32

22When you reap the harvest of your land, you are not to reap all the way to the edge of your field or gather the gleanings of your harvest. Leave them for the poor and the resident alien; I am the Lord your God.”

23The Lord spoke to Moses:

24“Tell the Israelites: In the seventh month, on the first day of the month, you are to have a day of complete rest, commemoration, and trumpet blasts  — a sacred assembly.

25You must not do any daily work, but you must present a food offering to the Lord.”

26The Lord again spoke to Moses:

27“The tenth day of this seventh month is the Day of Atonement. You are to hold a sacred assembly and practice self-denial; you are to present a food offering to the Lord.

28On this particular day you are not to do any work, for it is a Day of Atonement to make atonement for yourselves before the Lord your God.

29If any person does not practice self-denial on this particular day, he is to be cut off from his people.

30I will destroy among his people anyone who does any work on this same day.

31You are not to do any work. This is a permanent statute throughout your generations wherever you live.

32It will be a Sabbath of complete rest for you, and you must practice self-denial. You are to observe your Sabbath from the evening of the ninth day of the month until the following evening.”
