And ye shall take them as an inheritance for your children after you, to inherit them for a possession; they shall be your bondmen for ever: but over your brethren the children of Israel, ye shall not rule one over another with rigour.
You may make them an inheritance for your children after you, to hold for a possession. Of them you may take your slaves forever, but over your brothers the children of Israel you shall not rule, one over another, with harshness.
