Leviticus 25:39-41

39And if thy brotherthat dwelleth by thee shall have become poor, and be sold to thee; thou shalt not compel him to serve as a slave:1 40But as an 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.
