Leviticus 23:20-22

King James Version

²⁰ And the priest shall wave them with the bread of the firstfruits for a wave offering before the Lord, with the two lambs: they shall be holy to the Lord for the priest.

²¹ And ye shall proclaim on the selfsame day, that it may be an holy convocation unto you: ye shall do no servile work therein: it shall be a statute for ever in all your dwellings throughout your generations.

²² And when ye reap the harvest of your land, thou shalt not make clean riddance of the corners of thy field when thou reapest, neither shalt thou gather any gleaning of thy harvest: thou shalt leave them unto the poor, and to the stranger: I am the Lord your God.
