²² The likeness of the expanse over the heads of the living creatures was as the awesome gleam of crystal, stretched out over their heads above. ²³ Under the expanse their wings were stretched out straight, the one toward the other. Each one also had two wings which covered its body on the one side and the other. ²⁴ When they went, I heard the noise of their wings, like the noise of abundant waters, as the voice of the Almighty, the noise of tumult as the noise of an army camp. Whenever they stood still, they let down their wings.
