Darkness: Degrees of, Mentioned: Thick

The LORD spoke these commandments in a loud voice to your whole assembly out of the fire, the cloud, and the deep darkness on the mountain; He added nothing more. And He wrote them on two tablets of stone and gave them to me.

…a day of darkness and gloom, a day of clouds and blackness. Like the dawn overspreading the mountains a great and strong army appears, such as never was of old, nor will ever be in ages to come.
