Law of Divorce
19“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. 20When 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.
Deuteronomy 24:19-21 (NASB)
