Deuteronomy 24:22 YLT

²⁰  'When thou beatest thine olive, thou dost not examine the branch behind thee; to the sojourner, to the fatherless, and to the widow, it is.

²¹  'When thou cuttest thy vineyard, thou dost not glean behind thee; to the sojourner, to the fatherless, and to the widow, it is;

²²  and thou hast remembered that a servant thou hast been in the land of Egypt; therefore I am commanding thee to do this thing.
