'Utterly' in the Bible

The ten horns which you saw, and the beast, these will hate the prostitute, and will make her desolate, and will make her naked, and will eat her flesh, and will burn her utterly with fire.

Therefore in one day her plagues will come: death, mourning, and famine; and she will be utterly burned with fire; for the Lord God who has judged her is strong.
