Leviticus 25:43
“Thou shalt not rule over him with rigour; but shalt fear thy God.”
And 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.
For they are my servants, which I brought forth out of the land of Egypt: they shall not be sold as bondmen.
Thou shalt not rule over him with rigour; but shalt fear thy God.
Both thy bondmen, and thy bondmaids, which thou shalt have, shall be of the heathen that are round about you; of them shall ye buy bondmen and bondmaids.
Moreover 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 begat in your land: and they shall be your possession.
