Deuteronomy 24:19-21

TKJU(i) 19 When you cut down your harvest in your field, and have forgot a sheaf in the field, you shall not go again to fetch it: It shall be for the stranger, for the fatherless, and for the widow: That the LORD your God may bless you in all the work of your hands. 20 When you beat your olive tree, you shall not go over the boughs again: It shall be for the stranger, for the fatherless, and for the widow. 21 When you gather the grapes of your vineyard, you shall not glean it afterward: It shall be for the stranger, for the fatherless, and for the widow.
