Joshua 11:1, 10, 11

When Jabin king of Hazor heard of this, he sent word to Jobab king of Madon, to the kings of Shimron and Akshaph

At that time Joshua turned back and captured Hazor and put its king to the sword. (Hazor had been the head of all these kingdoms.)

Everyone in it they put to the sword. They totally destroyed them, not sparing anyone that breathed, and he burned Hazor itself.
