15 As I looked at the creatures, suddenly there was a wheel on the earth corresponding to all four faces of the creatures.
16 The appearance and composition of the wheels were like sparkling topaz. There was one shape for all four of them, as if one wheel were inside another.
17 When they moved in any of the four directions, they moved without swerving.
18 Their rims were tall and terrifying, because all four of them were filled with eyes all around.
19 When the creatures moved, the wheels moved next to them. Whenever the creatures rose above the earth, the wheels also rose up.
20 Wherever the wind would appear to go, the wind would make them go there too. The wheels rose up beside them, because the spirit of the creatures was in the wheels.
21 When they moved, the wheels moved; when they stood still, the wheels stood still; and when they rose above the earth, the wheels rose up along with them, because the spirit of the creatures was in the wheels.
