Leviticus 25:42-46

KJ2000(i) 42 For they are my servants, whom I brought forth out of the land of Egypt: they shall not be sold as slaves. 43 You shall not rule over him with harshness; but shall fear your God. 44 Both your male and female slaves, whom you shall have, shall be of the nations that are round about you; of them shall you buy male and female slaves. 45 Also of the children of the strangers that do sojourn among you, of them shall you buy, and of their families that are with you, whom they begat in your land: and they shall be your possession. 46 And you shall take them as an inheritance for your children after you, to inherit them for a possession; they shall be your slaves forever: but over your brethren the children of Israel, you shall not rule one over another with harshness.
