Joshua 11:12 KJV

10And Joshua at that time turned back, and took Hazor, and smote the king thereof with the sword: for Hazor beforetime was the head of all those kingdoms.

11And they smote all the souls that were therein with the edge of the sword, utterly destroying them: there was not any left to breathe: and he burnt Hazor with fire.

12And all the cities of those kings, and all the kings of them, did Joshua take, and smote them with the edge of the sword, and he utterly destroyed them, as Moses the servant of the LORD commanded.

13But as for the cities that stood still in their strength, Israel burned none of them, save Hazor only; that did Joshua burn.

14And all the spoil of these cities, and the cattle, the children of Israel took for a prey unto themselves; but every man they smote with the edge of the sword, until they had destroyed them, neither left they any to breathe.
