Leviticus 25:46

You may leave them to your sons after you to inherit as property; you can make them slaves for life. But as for your brothers, the Israelites, no man may rule harshly over his brother.

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.

Note they…: Heb. ye shall serve yourselves with them

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.

And ye shall make them an inheritance for your children after you, to hold for a possession; of them shall ye take your bondmen for ever: but over your brethren the children of Israel ye shall not rule, one over another, with rigor.
