'Black' in the Bible

Let the dark and the black night take it for themselves; let it be covered with a cloud; let the dark shades of day send fear on it.

Before I go to the place from which I will not come back, to the land where all is dark and black,

For I am overcome by the dark, and by the black night which is covering my face.

My skin is black and dropping off me; and my bones are burning with the heat of my disease.
