Laws Against Oppression and Usury

Leviticus 25:35-38

If thy brother be impoverished, and weak of hand, and thou receive him as a stranger and sojourner, and he live with thee:

Take not usury of him nor more than thou gavest. Fear thy God, that thy brother may live with thee.

Thou shalt not give him thy money upon usury: nor exact of him any increase of fruits.

I am the Lord your God, who brought you out of the land of Egypt, that I might give you the land of Chanaan, and might be your God.
