Ezekiel 1:22-26

Now stretched over the heads of the living beings there was something like an expanse, looking like the terrible and awesome shimmer of icy crystal. Under the expanse their wings were stretched out straight, one toward another. Every living being had two wings which covered its body on one side and on the other side. As they moved, I also heard the sound of their wings like the sound of great [rushing] waters, like the voice of the Almighty, the sound of tumult like the noise of an army camp. Whenever they came to a stop, they lowered their wings. And there was a voice above the expanse that was over their heads; whenever they stopped, they lowered their wings. Now 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. [Phil 2:5-8]
