Leviticus 25:39-41

39And if thy brother that dwelleth by thee be waxen poor, and be sold unto thee; thou shalt not compel him to serve as a bondservant:1 40But as an hired servant, and as a sojourner, he shall be with thee, and shall serve thee unto the year of jubile: 41And then shall he depart from thee, both he and his children with him, and shall return unto his own family, and unto the possession of his fathers shall he return.
