Joshua 11:1-5, 10-11

When Jabin, king of Hazor, heard of this, he sent to Jobab king of Madon, and to the king of Shimron, and to the king of Achshaph, and to the kings who were in the northern hill country, and in the Arabah south of Chinneroth, and in the lowland, and in Naphoth-dor on the west, to the Canaanites in the east and the west, the Amorites, the Hittites, the Perizzites, and the Jebusites in the hill country, and the Hivites under Hermon in the land of Mizpah. And they came out with all their troops, a great horde, in number like the sand that is on the seashore, with very many horses and chariots. And all these kings joined their forces and came and encamped together at the waters of Merom to fight against Israel.

And Joshua turned back at that time and captured Hazor and struck its king with the sword, for Hazor formerly was the head of all those kingdoms. And they struck with the sword all who were in it, devoting them to destruction; there was none left that breathed. And he burned Hazor with fire.
