Deuteronomy 24:21

¹⁹And when thou shalt have reaped corn in thy field, and shalt have forgotten a sheaf in thy field, thou shalt not return to take it; it shall be for the stranger, and the orphan, and the widow, that the Lord thy God may bless thee in all the works of thy hands.

²⁰And if thou shouldest gather thine olives, thou shalt not return to collect the remainder; it shall be for the stranger, and the fatherless, and the widow, and thou shalt remember that thou wast a bondman in the land of Egypt; therefore I command thee to do this thing.
