Joshua 11:10-13

11:10 At that time Joshua turned, captured Hazor, and struck down its king with the sword, for Hazor was at that time the leader of all these kingdoms. 11:11 They annihilated everyone who lived there with the sword – no one who breathed remained – and burned Hazor.

11:12 Joshua captured all these royal cities and all their kings and annihilated them with the sword, as Moses the Lord’s servant had commanded. 11:13 But Israel did not burn any of the cities located on mounds, except for Hazor; it was the only one Joshua burned.
