²² Over the head of the [combined] living creature there was the likeness of a firmament, looking like the terrible and awesome [dazzling of shining] crystal or ice stretched across the expanse of sky over their heads.

²³ And under the firmament their wings were stretched out straight, one toward another. Every living creature had two wings which covered its body on this side and two which covered it on that side.

²⁴ And when they went, I heard the sound of their wings like the noise of great waters, like the voice of the Almighty, the sound of tumult like the noise of a host. When they stood, they let down their wings.
