Deuteronomy 24:17-21

“You shall not pervert the justice due a stranger or an orphan, nor seize a widow’s garment as a pledge.

But you are to remember that you were a slave in Egypt, and that the Lord your God redeemed you from there; therefore I am commanding you to do this thing.

“When you reap your harvest in your field and forget a sheaf in the field, you are not to go back to get it; it shall belong to the stranger, the orphan, and to the widow, in order that the Lord your God may bless you in all the work of your hands.

When you beat the olives off your olive tree, you are not to search through the branches again; that shall be left for the stranger, the orphan, and for the widow.

“When you gather the grapes of your vineyard, you are not to go over it again; that shall be left for the stranger, the orphan, and the widow.
