Ezekiel 1:14-18

And the living beings ran back and forth like bolts of lightning.

Now as I looked at the living beings, behold, there was one wheel on the ground beside the living beings, for each of the four of them.

The appearance of the wheels and their workmanship was like sparkling topaz, and all four of them had the same form, their appearance and workmanship being as if one wheel were within another.

Whenever they moved, they moved in any of their four directions without turning as they moved.

As for their rims, they were high and awesome, and the rims of all four of them were covered with eyes all around.
