Verses with the word rigour in the Old Testament (5 verses):
And the Egyptians made the children of Israel to serve with rigour:
And they made their lives bitter with hard bondage, in morter, and in brick, and in all manner of service in the field: all their service, wherein they made them serve, was with rigour.
Thou shalt not rule over him with rigour; but shalt fear thy God.
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.
And as a yearly hired servant shall he be with him: and the other shall not rule with rigour over him in thy sight.
