Ezekiel 1:25-28

Then there came a voice from above the vault over their heads as they stood with lowered wings. Above the vault over their heads was what looked like a throne of lapis lazuli, and high above on the throne was a figure like that of a man. 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. 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 the LORD. When I saw it, I fell facedown, and I heard the voice of one speaking.
