They did not destroy the nations,.... Here begins an account of their sins and provocations, after they were settled in the land of Canaan. They did not destroy the inhabitants of the land, of the seven nations; whose land was given to them as an inheritance, and of which the Canaanites were dispossessed for their sins, and to be destroyed.
Concerning whom the Lord commanded them; that they should destroy them; the command is in De 7:1. God's commands are to be obeyed; they are neither to be added to, nor diminished from; his commands are transgressed and violated by sins of omission or commission; the Israelites might plead mercy, but this was no excuse to an express command: the same sin Saul was afterwards guilty of, with respect to one of these nations, 1Sa 15:2.
