'Blackness' in the Bible

For ye are not come unto the mount that might be touched, and that burned with fire, nor 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.

Raging waves of the sea, foaming out their own shame; wandering stars, to whom is reserved the blackness of darkness for ever.
