Ezekiel 10:9-11

New Catholic Bible

⁹ As I looked on, I saw that there were four wheels beside the cherubim, one wheel beside each cherub, and the wheels had the appearance of sparkling chrysolite. ¹⁰ As for their appearance, all four seemed to be identical, something like a wheel within a wheel.

¹¹ When the cherubim moved, they went in any of the four directions without veering from their course. In whatever direction the front wheel faced, the others followed without swerving as they moved.
