'Blazing' in the Bible

You came near and stood at the base of the mountain, a mountain blazing with fire into the heavens and enveloped in a dense, black cloud.

All of you approached me with your tribal leaders and elders when you heard the voice from the darkness and while the mountain was blazing with fire.

“So I went back down the mountain, while it was blazing with fire, and the two tablets of the covenant were in my hands.
