Leviticus 25:37-41

³⁷Thou shalt not give him thy money for usury, nor thy food for increase.

³⁸I am the Lord your God, who brought you out from the land of Mizraim, to give you the land of Kenaan, and to be your God.

³⁹And if thy brother hath become poor with thee, and hath sold himself to thee, thou shalt not make him do the works of slaves,

⁴⁰But as a hired man and an inmate shall he be with thee; until the year of Jubilee shall he serve with thee:

⁴¹Then shall he go out from being with thee, he and his children with him, and return to his family and to the inheritance of his fathers.
