Josh 11:10-15

10Joshua turned back at that time, and took Hazor, and struck its king down with the sword. Before that time Hazor was the head of all those kingdoms.11And they put to the sword all who were in it, utterly destroying them; there was no one left who breathed, and he burned Hazor with fire.12And all the towns of those kings, and all their kings, Joshua took, and struck them with the edge of the sword, utterly destroying them, as Moses the servant of the Lord had commanded.13But Israel burned none of the towns that stood on mounds except Hazor, which Joshua did burn.14All the spoil of these towns, and the livestock, the Israelites took for their booty; but all the people they struck down with the edge of the sword, until they had destroyed them, and they did not leave any who breathed.15As 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.
