Leviticus 23:22-25

²²And when ye reap the harvest of your land, thou shalt not wholly reap the corners of thy field, neither shalt thou gather the gleaning of thy harvest: thou shalt leave them for the poor, and for the sojourner: I am Jehovah your God.

²³And Jehovah spake unto Moses, saying,

²⁴Speak unto the children of Israel, saying, In the seventh month, on the first day of the month, shall be a solemn rest unto you, a memorial of blowing of trumpets, a holy convocation.

²⁵Ye shall do no servile work; and ye shall offer an offering made by fire unto Jehovah.
