'Blackness' in the Bible

Whoever curses 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."

That day is a day of wrath, a day of distress and anguish, a day of trouble and ruin, a day of darkness and gloom, a day of clouds and blackness,

For you have not come to a mountain that might be touched, and that burned with fire, and to blackness, darkness, storm,

These are wells without water, clouds driven by a storm; for whom the blackness of darkness has been reserved forever.

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