Deuteronomy 24:17-22

17You must not pervert justice due a resident foreigner or an orphan, or take a widow’s garment as security for a loan.

18Remember that you were slaves in Egypt and that the Lord your God redeemed you from there; therefore I am commanding you to do all this.

19Whenever you reap your harvest in your field and leave some unraked grain there, you must not return to get it; it should go to the resident foreigner, orphan, and widow so that the Lord your God may bless all the work you do.

20When you beat your olive tree you must not repeat the procedure; the remaining olives belong to the resident foreigner, orphan, and widow.

21When you gather the grapes of your vineyard you must not do so a second time; they should go to the resident foreigner, orphan, and widow.

22Remember that you were slaves in the land of Egypt; therefore, I am commanding you to do all this.
