Ezekiel 1:16-20

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.

Whenever the living beings moved, the wheels moved with them. And whenever the living beings rose from the earth, the wheels rose also.

Wherever the spirit was about to go, they would go in that direction. And the wheels rose just as they did; for the spirit of the living beings was in the wheels.
