Ezekiel 1:26-28

26Above the expanse over their heads was the likeness of a throne with the appearance of sapphire, and on the throne high above was a figure like that of a man. 27From what seemed to be His waist up, I saw a gleam like amber, with what looked like fire within it all around. And from what seemed to be His waist down, I saw what looked like fire; and brilliant light surrounded Him.

28The appearance of the brilliant light all around Him was like that of a rainbow in a cloud on a rainy day. This was the appearance of the likeness of the glory of the LORD. And when I saw it, I fell facedown and heard a voice speaking.
