'Thick Cloud' in the Bible

And his voice will be loud over him in that day like the sounding of the sea: and if a man's eyes are turned to the earth, it is all dark and full of trouble; and the light is made dark by thick clouds.

I have put your evil doings out of my mind like a thick cloud, and your sins like a mist: come back to me; for I have taken up your cause.
