Deuteronomy 23:20

You may charge a foreigner interest , but you may not charge your brother interest , that the Lord your God may bless you in all that you undertake in the land that you are entering to take possession of it.

You may charge a foreigner interest, but not a fellow Israelite, so that the Lord your God may bless you in everything you put your hand to in the land you are entering to possess.

Unto a stranger thou mayest lend upon usury; but unto thy brother thou shalt not lend upon usury : that the Lord thy God may bless thee in all that thou settest thine hand to in the land whither thou goest to possess it.
