Ezekiel 10:9-11

New Revised Standard Version Catholic Edition

⁹ I looked, and there were four wheels beside the cherubim, one beside each cherub; and the appearance of the wheels was like gleaming beryl. ¹⁰ And as for their appearance, the four looked alike, something like a wheel within a wheel. ¹¹ When they moved, they moved in any of the four directions without veering as they moved; but in whatever direction the front wheel faced, the others followed without veering as they moved.
