'Dense' in the Bible

Behold, the name of the Lord comes from a remote place;Burning is His anger and dense is His smoke;His lips are filled with indignationAnd His tongue is like a consuming fire;

“Through your servants you have taunted and defied the Lord,And you have said, ‘With my many chariots I have gone up to the heights of the mountains,To the remotest parts of Lebanon.I cut down its tallest cedars and its choicest cypress trees;And I will go to its remotest height, its most luxuriant and thickest forest.

“For in fact, darkness will cover the earthAnd deep darkness will cover the peoples;But the Lord will rise upon you [Jerusalem]And His glory and brilliance will be seen on you.
