Ezekiel 10:9 KJV

7And one cherub stretched forth his hand from between the cherubims unto the fire that was between the cherubims, and took thereof, and put it into the hands of him that was clothed with linen: who took it, and went out.

8And there appeared in the cherubims the form of a man’s hand under their wings.

9And when I looked, behold the four wheels by the cherubims, one wheel by one cherub, and another wheel by another cherub: and the appearance of the wheels was as the colour of a beryl stone.

10And as for their appearances, they four had one likeness, as if a wheel had been in the midst of a wheel.

11When they went, they went upon their four sides; they turned not as they went, but to the place whither the head looked they followed it; they turned not as they went.
