'Utterly' in the Bible

For the children of Ammon and Moab stood up against the inhabitants of mount Seir, utterly to slay and destroy them: and when they had made an end of the inhabitants of Seir, every one helped to destroy another.

Now when all this was finished, all Israel that were present went out to the cities of Judah, and brake the images in pieces, and cut down the groves, and threw down the high places and the altars out of all Judah and Benjamin, in Ephraim also and Manasseh, until they had utterly destroyed them all. Then all the children of Israel returned, every man to his possession, into their own cities.

Who was there among all the gods of those nations that my fathers utterly destroyed, that could deliver his people out of mine hand, that your God should be able to deliver you out of mine hand?
