'Completely' in the Bible

So the Lord our God gave up Og, king of Bashan, and all his people into our hands; and we overcame him so completely that all his people came to their end in the fight.

The Lord will have no mercy on him, but the wrath of the Lord will be burning against that man, and all the curses recorded in this book will be waiting for him, and the Lord will take away his name completely from the earth.
