Ezekiel 1:26-27

26Now above the expanse that was over their heads there was something resembling a throne, it appeared like [it was made of] sapphire or lapis lazuli; and [seated] on that which looked like a throne, high up, was a figure with the appearance of a man.

27Now upward, from that which appeared to be His waist, I saw something like glowing metal that looked like it was filled with fire all around it; and downward, from that which appeared to be His waist, I saw something like fire; and there was a brightness and a remarkable radiance [like a halo] around Him.
