'Blackness' in the Bible

Whoso curseth his father or his mother, His lamp shall be put out in blackness of darkness.

I clothe the heavens with blackness, and I make sackcloth their covering.

For ye are not come unto a mount that might be touched, and that burned with fire, and unto blackness, and darkness, and tempest,

These are springs without water, and mists driven by a storm; for whom the blackness of darkness hath been reserved.

Wild waves of the sea, foaming out their own shame; wandering stars, for whom the blackness of darkness hath been reserved forever.
