Compare Exodus 20:8, Exodus 20:12; Exodus 31:13-14. The two laws repeated here are the only laws in the Decalogue which assume a positive shape, all the others being introduced by the formula, “Thou shalt not.” These express two great central points, the first belonging to natural law and the second to positive law, in the maintenance of the well-being of the social body of which Yahweh was the acknowledged king.
