Ezekiel 1:27-28

27 I saw that from what appeared to be His waist up He looked like glowing metal, as if full of fire, and that from there down He looked like fire; and brilliant light surrounded Him.

28 Like the appearance of a rainbow in the clouds on a rainy day, so was the radiance around Him.   This was the appearance of the likeness of the glory of Yahveh.   When I saw it, I fell facedown, and I heard the voice of one speaking.
