'Utter' in the Bible

These men are waterless springs and mists driven by a storm, for whom the utter depths of darkness have been reserved.

You also know that the angels who did not keep within their proper domain but abandoned their own place of residence, he has kept in eternal chains in utter darkness, locked up for the judgment of the great Day.

wild sea waves, spewing out the foam of their shame; wayward stars for whom the utter depths of eternal darkness have been reserved.
