Deuteronomy 23:20

Thou shalt not lend to thy brother on usury of silver, or usury of meat, or usury of any thing which thou mayest lend out.

You may lend on usury to a stranger, but to your brother you shall not lend on usury; that the Lord your God may bless you in all your works upon the land, into which you are entering to inherit it.

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.
