Exodus 1:14 And they made their lives bitter with hard bondage, in mortar, and in brick, and in all manner of service in the field; all their service, wherein they made them serve, was with
rigor.
Leviticus 25:46 And ye shall take them as an inheritance for your children after you, to inherit them for a possession; they shall be your bond-men for ever; but over your brethren the children of Israel, ye shall not rule one over another with
rigor.
