And above the firmament over their heads was the likeness of a throne, in appearance like a sapphire stone; on the likeness of the throne was a likeness with the appearance of a man high above it.  Also from the appearance of His waist and upward I saw, as it were, the color of amber with the appearance of fire all around within it; and from the appearance of His waist and downward I saw, as it were, the appearance of fire with brightness all around.  Like the appearance of a rainbow in a cloud on a rainy day, so was the appearance of the brightness all around it.  This was the appearance of the likeness of the glory of the Lord.  So when I saw it, I fell on my face, and I heard a voice of One speaking.

Eze 1:26-28   (NKJV)
