Ezekiel 1:11

Thus were their faces: and their wings were stretched upward. — Rather, and their wings and their faces were separated above. The word never has the sense of stretched, but always that of separated or divided, as given in the margin. Each cherub was essentially one creature, and yet (not Janus-like, with four faces upon one head) their heads and their wings were separated above, and when they were in flight the two lifted wings touched on either side the wing of the next cherub, while two were used to veil their bodies. There is much of emphatic repetition throughout the description.
