Leviticus 25:37-41

³⁷Thou shalt not lend thy money to him at interest, and thou shalt not lend thy meat to him to be returned with increase.

³⁸I am the Lord your God, who brought you out of the land of Egypt, to give you the land of Chanaan, so as to be your God.

³⁹And if thy brother by thee be lowered, and be sold to thee, he shall not serve thee with the servitude of a slave.

⁴⁰He shall be with thee as a hireling or a sojourner, he shall work for thee till the year of release:

⁴¹and he shall go out in the release, and his children with him; and he shall go to his family, he shall hasten back to his patrimony.
