Leviticus 25:37-41

³⁷Thou shalt not give to him thy money to usury, and thou shalt not ask over that that thou lendest, increases of fruits;

³⁸I am your Lord God, that led you out of the land of Egypt, that I should give to you the land of Canaan, and that I should be your God.

³⁹If thy brother compelled by poverty selleth himself to thee, thou shalt not oppress him by servage of servants,

⁴⁰but he shall be as an hired man and a tenant; till to the year of jubilee he shall work with thee,

⁴¹and afterward he shall go out with his free children, and he shall turn again to his kindred, and to the possession of his fathers.
