positive law

We know that generally in all commonwealths, the execution of corporal punishments, was either put upon the guards, or other soldiers of the sovereign power; or given to those, in whom want of means, contempt of honour, and hardness of heart, concurred, to make them sue for such an office. But amongst the Israelites it was a positive law of God their sovereign, that he that was convicted of a capital crime, should be stoned to death by the people.
