Ezekiel 10:9-12

9Then I looked, and behold, four wheels beside the cheruvim, one wheel beside one cheruv, and another wheel beside another cheruv. The appearance of the wheels was like the sparkling of a beryl stone.

10As for their appearance, the four had one form—like a wheel within a wheel.

11When they went, they would go in any of their four directions, without pivoting as they went. So to whatever place the head faced, they followed, without turning as they went.

12Their whole body, their backs, their hands, their wings, and their wheels, the wheels of the four of them, were full of eyes all around.
