11 Such were their faces. They each had two wings spreading out upward, each wing touching that of the creature on either side; and each had two other wings covering its body.
12 Each one went straight ahead. Wherever the spirit would go, they would go, without turning as they went.
13 The appearance of the living creatures was like burning coals of fire or like torches. Fire moved back and forth among the creatures; it was bright, and lightning flashed out of it.
14 The creatures sped back and forth like flashes of lightning.
15 As I looked at the living creatures, I saw a wheel on the ground beside each creature with its four faces.
16 This was the appearance and structure of the wheels: They sparkled like topaz, and all four looked alike. Each appeared to be made like a wheel intersecting a wheel.
17 As they moved, they would go in any one of the four directions the creatures faced; the wheels did not change direction as the creatures went.
