'Thick' in the Bible

and they shall look unto the earth, and behold, distress and darkness, the gloom of anguish; and into thick darkness they shall be driven away.

Behold, the name of Jehovah cometh from far, burning with his anger, and in thick rising smoke: his lips are full of indignation, and his tongue is as a devouring fire;

I have blotted out, as a thick cloud, thy transgressions, and, as a cloud, thy sins: return unto me; for I have redeemed thee.
