Leviticus 23:20-22

Revised Standard Version

²⁰ And the priest shall wave them with the bread of the first fruits as a wave offering before the Lord, with the two lambs; they shall be holy to the Lord for the priest. ²¹ And you shall make proclamation on the same day; you shall hold a holy convocation; you shall do no laborious work: it is a statute for ever in all your dwellings throughout your generations.

²² “And when you reap the harvest of your land, you shall not reap your field to its very border, nor shall you gather the gleanings after your harvest; you shall leave them for the poor and for the stranger: I am the Lord your God.”
