'Darkness' in the Bible

and have persuaded yourself that, as for you, you are a guide to the blind, a light to those who are in darkness,

Let darkness come over their eyes that they may be unable to see, and make Thou their backs continually to stoop."

The night is far advanced, and day is about to dawn. We must therefore lay aside the deeds of darkness, and clothe ourselves with the armour of Light.
