²² And over the heads of each living creature there appeared a heaven like a marvellous crystal, stretched forth over their heads above.

²³ And under the heaven their wings were straight, one toward the other: each one had two, and another two which covered their bodies.

²⁴ And when they went, I heard the noise of their wings, like the noise of many waters, as the voice of the Almighty, when they went; the voice of the word, as the voice of an army. When they stood, they let down their wings.
