Ezekiel 10:9-12

9I looked, and I saw beside the cherubim four wheels, one beside each of the cherubim; the wheels sparkled like topaz.

10As for their appearance, the four of them looked alike; each was like a wheel intersecting a wheel.

11As they moved, they would go in any one of the four directions the cherubim faced; the wheels did not turn about as the cherubim went. The cherubim went in whatever direction the head faced, without turning as they went.

12Their entire bodies, including their backs, their hands and their wings, were completely full of eyes, as were their four wheels.
