Joshua 11:1-5, 10-11

And it came to pass, when Jabin king of Hazor heard these things, that he sent to Jobab king of Madon, to the king of Shimron, to the king of Achshaph, and to the kings who were from the north, in the mountains, in the plain south of Chinneroth, in the lowland, and in the heights of Dor on the west, to the Canaanites in the east and in the west, the Amorite, the Hittite, the Perizzite, the Jebusite in the mountains, and the Hivite below Hermon in the land of Mizpah. So they went out, they and all their armies with them, as many people as the sand that is on the seashore in multitude, with very many horses and chariots. And when all these kings had met together, they came and camped together at the waters of Merom to fight against Israel.

Joshua turned back at that time and took Hazor, and struck its king with the sword; for Hazor was formerly the head of all those kingdoms. And they struck all the people who were in it with the edge of the sword, utterly destroying them. There was none left breathing. Then he burned Hazor with fire.
