Joshua 11:1-5, 10-11

When the news of Israel’s southern victories reached King Jabin of Hazor, he organized a massive coalition to fight against Israel. He sent messages to: King Jobab of Merom, the king of Shimron, the king of Achshaph, the kings of the northern hill country, the kings of the Jordan Valley south of Lake Galilee, the kings of the foothills, the western kings in the heights of Dor, the eastern and western Canaanite kings, the Amorite kings, the Hittite kings, the Perizzite kings, the Jebusite kings in the highlands, and the Hivite kings who lived near Mount Hermon in the land of Mizpah. They came out in full force with a multitude of horses and chariots. Their vast armies were as numerous as the grains of sand on the seashore. All these kings and their enormous armies joined forces and encamped at Lake Merom to fight against Israel.

Because Hazor at that time was the most powerful of all these kingdoms, Joshua circled back after the battle and conquered it. They killed the king, burned Hazor to the ground, and annihilated all its inhabitants. They spared not one breathing thing, leaving no survivors.
