'Utterly' in the Bible

Then the Lord said to Moses, “Write this in a book as a memorial and recite it to Joshua, that I will utterly blot out the memory of Amalek from under heaven.”

“He who sacrifices to any god, other than to the Lord alone, shall be utterly destroyed.

You shall not worship their gods, nor serve them, nor do according to their deeds; but you shall utterly overthrow them and break their sacred pillars in pieces.
