Leviticus 23:22-25

²²When you harvest the crops grown on your land, don't harvest right up to the edges of your field, or collect what has been missed. Leave them for the poor people and foreigners. I am the Lord your God.”

²³The Lord told Moses,

²⁴“Tell the Israelites that on the first day of the seventh month you are to have a special Sabbath of complete rest, a holy meeting that is announced by the sound of trumpets.

²⁵Don't do any of your usual work; instead you are to present a food offering to the Lord.”
