'Utterly' in the Bible

Because he has despised and rejected the word of the Lord, and has broken His commandment, that person shall be utterly cut off; [the responsibility for] his wickedness and guilt will be upon him.’”

So Israel made a vow to the Lord, and said, “If You will indeed hand over these people to me, then I will utterly destroy their cities.”

The Lord heard the voice of Israel and handed over the Canaanites; then they utterly destroyed them and their cities. So the name of the place was called Hormah (dedicate to destruction).
