Vayikra 23:20-22

Orthodox Jewish Bible

²⁰ And the kohen shall wave them with the lechem of the bikkurim for a wave offering before Hashem, with the two kevasim; they shall be kodesh to Hashem for the kohen.

²¹ And ye shall proclaim on the same day, that it may be a mikra kodesh unto you; ye shall do no melekhet avodah therein; it shall be a chukkat olam in all your dwellings throughout your dorot.

²² And when ye reap the harvest of your land, thou shalt not reap to the edges of thy sadeh when thou reapest, neither shalt thou gather the gleanings of thy harvest; thou shalt leave them unto the oni (poor), and to the ger: I am Hashem Eloheichem.
