Deuteronomy 24
17 Ref You shall not wrest the justice [due] to the foreigner, [or] to the fatherless, nor take the widow's clothing to pledge;
18 Ref but you shall remember that you were a bondservant in Egypt, and Yahweh your God redeemed you there: therefore I command you to do this thing.
19 Ref When you reap your harvest in your field, and have forgot a sheaf in the field, you shall not go again to get it: it shall be for the foreigner, for the fatherless, and for the widow; that Yahweh your God may bless you in all the work of your hands.
20 Ref When you beat your olive tree, you shall not go over the boughs again: it shall be for the foreigner, for the fatherless, and for the widow.
21 Ref When you gather [the grapes of] your vineyard, you shall not glean it after you: it shall be for the foreigner, for the fatherless, and for the widow.
