'Interest' in the Bible

Do not take interest from an Israelite on anything, money or food or any other goods, which you let him have

From men of other nations you may take interest, but not from an Israelite: so that the blessing of the Lord your God may be on everything to which you put your hand, in the land which you are about to take as your heritage.

He will let you have his wealth at interest, and will have no need of yours: he will be the head and you the tail.
