Joshua 11:1-5, 10-11

When Jabin king of Hazor heard about all that had happened, he sent messages to Jobab king of Madon, to the king of Shimron, and to the king of Acshaph. He sent messages to the kings in the northern mountains and also to the kings in the Jordan Valley south of Lake Galilee and in the western hills. He sent a message to the king of Naphoth Dor in the west and to the kings of the Canaanites in the east and in the west. He sent messages to the Amorites, Hittites, Perizzites, and Jebusites in the mountains. Jabin also sent one to the Hivites, who lived below Mount Hermon in the area of Mizpah. So the armies of all these kings came together with their horses and chariots. There were as many soldiers as grains of sand on the seashore. All of these kings met together at the waters of Merom, joined their armies together into one camp, and made plans to fight against the Israelites.

Then Joshua went back and captured the city of Hazor and killed its king. (Hazor had been the leader of all the kingdoms that fought against Israel.) Israel killed everyone in Hazor, completely destroying them; no one was left alive. Then they burned Hazor itself.
