'Brilliant' in the Bible

I looked and there was a whirlwind coming from the north, a great cloud with fire flashing back and forth and brilliant light all around it. In the center of the fire, there was a gleam like amber.

From what seemed to be His waist up, I saw a gleam like amber, with what looked like fire enclosing it all around. From what seemed to be His waist down, I also saw what looked like fire. There was a brilliant light all around Him.

The appearance of the brilliant light all around was like that of a rainbow in a cloud on a rainy day. This was the appearance of the form of the Lord’s glory. When I saw it, I fell facedown and heard a voice speaking.
