Joshua 11:11-15

They struck every person who was in it with the edge of the sword, utterly destroying them; there was no one left who breathed. And he burned Hazor with fire.

Joshua captured all the cities of these kings, and all their kings; and he struck them with the edge of the sword and utterly destroyed them, just as Moses the servant of the Lord had commanded.

However, Israel did not burn any cities that stood on their mounds, except Hazor alone, which Joshua burned.

And all the spoils of these cities and the cattle, the sons of Israel took as their plunder; but they struck every person with the edge of the sword, until they had destroyed them. They left no one breathing.

Just as the Lord had commanded His servant Moses, so Moses commanded Joshua, and so Joshua did; he left nothing undone of all that the Lord had commanded Moses.
