Lev19:9 And when you get in the grain from your land, do not let all the grain be cut from the edges of the field, or take up what has been dropped on the earth after the getting in of the grain.
Lev23:22 And when you get in the grain from your land, do not let all the grain at the edges of the field be cut, and do not take up the grain which has been dropped in the field; let that be for the poor, and for the man from another country: I am the Lord your God.
