10 Joshua turned back at that time, and took Hazor, and struck its king with the sword: for Hazor used to be the head of all those kingdoms. 11 They struck all the souls who were in it with the edge of the sword, utterly destroying them. There was no one left who breathed. He burnt Hazor with fire. 12 Joshua captured all the cities of those kings, with their kings, and he struck them with the edge of the sword, and utterly destroyed them; as Moses the servant of Yahweh commanded. 13 But as for the cities that stood on their mounds, Israel burned none of them, except Hazor only. Joshua burned that.

Commentary on Joshua 11:10-14
(Read Joshua 11:10-14)
The Canaanites filled up the measure of their iniquity, and were, as a judgment, left to the pride, obstinacy, and enmity of their hearts, and to the power of Satan; all restraints being withdrawn, while the dispensations of Providence tended to drive them to despair. They brought on themselves the vengeance they justly merited, of which the Israelites were to be executioners, by the command the Lord gave to Moses.
