'Annihilated' in the Bible

So Joshua captured and annihilated all of these cities, along with their kings, completely destroying them, just as Moses the servant of the LORD had commanded.

At that time Joshua came and annihilated the Anakim from the hill country, that is, from Hebron, Debir, and Anab, as well as from all the hill country of Judah and Israel. Joshua completely destroyed them along with their cities.
