14. And the living creatures ran back and forth like the appearance of a flash of lightning.
15. Now as I beheld the living creatures, behold, a wheel upon the earth beside the living creatures, with its four faces.
16. The appearance of the wheels and their workings was like the color of beryl: and the four had the same likeness: and their appearance and their workings was, as it were, a wheel in the middle of a wheel.
17. When they went, they went in any of four directions: and they turned not when they went.
