You may charge a foreigner interest, but not your brother, so that the LORD your God may bless you in everything to which you put your hand in the land that you are entering to possess.
Jewish Publication Society of America Version (JPS1917) - Deuteronomy 23:20 >(23-21) Unto a foreigner thou mayest lend upon interest; but unto thy brother thou shalt not lend upon interest; that the LORD thy God may bless thee in all that thou puttest thy hand unto, in the land whither thou goest in to possess it.
