Leviticus

³⁹And if thy brother be waxen poor with thee, and sell himself unto thee; thou shalt not make him to serve as a bondservant: ⁴⁰as an hired servant, and as a sojourner, he shall be with thee; he shall serve with thee unto the year of jubile: ⁴¹then shall he go out 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. ⁴²For they are my servants, which I brought forth out of the land of Egypt: they shall not be sold as bondmen. ⁴³Thou shalt not rule over him with rigour; but shalt fear thy God. ⁴⁴And as for thy bondmen, and thy bondmaids, which thou shalt have; of the nations that are round about you, of them shall ye buy bondmen and bondmaids. ⁴⁵Moreover of the children of the strangers that do sojourn among you, of them shall ye buy, and of their families that are with you, which they have begotten in your land: and they shall be your possession.
