Joshua 11:13-15

But as for the cities that stood on their mounds, Israel burned none of them, save Hazor only; that did Joshua burn. And 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 that breathed. As Jehovah commanded Moses his servant, so did Moses command Joshua: and so did Joshua; he left nothing undone of all that Jehovah commanded Moses.
