Deuteronomy 24
20 Ref When thou beatest thine olive-tree, thou shalt not go over the boughs again: it shall be for the sojourner, for the fatherless, and for the widow.
21 Ref When thou gatherest `the grapes of' thy vineyard, thou shalt not glean it after thee: it shall be for the sojourner, for the fatherless, and for the widow.
