Ezekiel 1:26-27

26And above the expanse that was over their heads was the likeness of a throne, as the appearance of a sapphire stone; and upon the likeness of the throne was a likeness as the appearance of a man above upon it.

27And I saw as the look of glowing brass, as the appearance of fire, within it round about; from the appearance of his loins and upward, and from the appearance of his loins and downward, I saw as it were the appearance of fire, and it had brightness round about.
