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 stranger: I am the LORD your God.

²³And the LORD spake unto Moses, saying,

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

²⁵Ye shall do no servile work: and ye shall offer an offering made by fire unto the LORD.
