Leviticus 25:39-41

39And if thy brother grow poor beside thee, and be sold unto thee, thou shalt not compel him to serve as a bondservant:

40as a hired servant, as a sojourner, shall he be with thee; until the year of jubilee shall he serve thee.

41Then shall he depart from thee, he and his children with him, and shall return unto his own family, and unto the possession of his fathers shall he return.
