Deuteronomy 5:22
These words the LORD spoke to all your assembly in the mount out of the middle of the fire, of the cloud, and of the thick darkness, with a great voice: and he added no more. And he wrote them in two tables of stone, and delivered them to me.

Joel 2:2
A day of darkness and of gloominess, a day of clouds and of thick darkness, as the morning spread on the mountains: a great people and a strong; there has not been ever the like, neither shall be any more after it, even to the years of many generations.
