11 That is what their faces were like. Their wings were spread upward; each had two wings touching that of another and two wings covering its body.
12 Each creature went straight ahead. Wherever the Spirit wanted to go, they went without turning as they moved.
13 The form of the living creatures was like the appearance of burning coals of fire and torches. Fire was moving back and forth between the living creatures; it was bright, with lightning coming out of it.
14 The creatures were darting back and forth like flashes of lightning.
15 When I looked at the living creatures, there was one wheel on the ground beside each creature that had four faces.
16 The appearance of the wheels and their craftsmanship was like the gleam of beryl, and all four had the same form. Their appearance and craftsmanship was like a wheel within a wheel.
17 When they moved, they went in any of the four directions, without pivoting as they moved.
