Ezekiel 1:22-26

Now over the heads of the living beings there was something like an expanse, like the awesome gleam of crystal, spread out over their heads.

Under the expanse their wings were stretched out straight, one toward the other; each one also had two wings covering its body on the one side and on the other.

And I also heard the sound of their wings, like the sound of abundant waters as they went, like the voice of the Almighty, a sound of a crowd like the sound of an army camp; whenever they stopped, they let down their wings.

And a voice came from above the expanse that was over their heads; whenever they stood still, they let down their wings.

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.
