Leviticus 23:15; Leviticus 23:22

15 “ ‘From the day after the Sabbath, the day you brought the sheaf of the wave offering, count off seven full weeks.

22 “ ‘When you reap the harvest of your land, do not reap to the very edges of your field or gather the gleanings of your harvest. Leave them for the poor and for the foreigner residing among you. I am the LORD your God.’ ”
