Leviticus 25:37-41

³⁷Thou shalt not give him thy money upon interest, nor lend him thy victuals for increase.

³⁸I am the LORD your God, who brought you out of the land of Egypt, to give you the land of Canaan, and to be your God.

³⁹And if thy brother that dwelleth by thee shall have become poor, and be sold to thee; thou shalt not compel him to serve as a bond servant:

⁴⁰But as a hired servant, and as a sojourner he shall be with thee, and shall serve thee to the year of jubilee.

⁴¹And then shall he depart from thee, both he and his children with him, and shall return to his own family, and to the possession of his fathers shall he return.
