Ezekiel 1:23-24
23
Under the expanse were their wings straight, the one toward the other: each one had two which covered on this side, and every one had two which covered on that side, their bodies.
24
When they went, I heard the noise of their wings like the noise of great waters, like the voice of the Almighty, a noise of tumult like the noise of an army: when they stood, they let down their wings.
