'Blackness' in the Bible

Let darkness and the shadow of death stain it; let a cloud dwell upon it; let the blackness of the day terrify it.

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

Before their face the people shall be much pained: all faces shall gather blackness.

She is empty, and void, and waste: and the heart melteth, and the knees smite together, and much pain is in all loins, and the faces of them all gather blackness.

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

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