Ezekiel 1:26-28

Now above the expanse that was over their heads there was something resembling a throne, like lapis lazuli in appearance; and on that which resembled a throne, high up, was a figure with the appearance of a man. Then I noticed from the appearance of His loins and upward something like glowing metal that looked like fire all around within it, and from the appearance of His loins and downward I saw something like fire; and there was a radiance around Him. As the appearance of the rainbow in the clouds on a rainy day, so was the appearance of the surrounding radiance. Such was the appearance of the likeness of the glory of the LORD. And when I saw it, I fell on my face and heard a voice speaking.
