Joshua 11:7-10

7So by the waters of Merom, Joshua and his whole army came upon them suddenly and attacked them, 8and the LORD delivered them into the hand of Israel, who struck them down and pursued them all the way to Greater Sidon and Misrephoth-maim, and eastward as far as the Valley of Mizpeh. They struck them down, leaving no survivors. 9Joshua treated them as the LORD had told him; he hamstrung their horses and burned up their chariots.

10At that time Joshua turned back and captured Hazor and put its king to the sword, because Hazor was formerly the head of all these kingdoms.
