'Glow' in the Bible

Its snorting throws out flashes of light; its eyes are like the red glow of dawn.

I saw an amber glow like a fire enclosed all around from his waist up. From his waist down I saw something that looked like fire. There was a brilliant light around it,

As I watched, I noticed a form that appeared to be a man. From his waist downward was something like fire, and from his waist upward something like a brightness, like an amber glow.
