Ezekiel 1:15-17

New Revised Standard Version Catholic Edition

¹⁵ As I looked at the living creatures, I saw a wheel on the earth beside the living creatures, one for each of the four of them.^{[a] 16} As for the appearance of the wheels and their construction: their appearance was like the gleaming of beryl; and the four had the same form, their construction being something like a wheel within a wheel. ¹⁷ When they moved, they moved in any of the four directions without veering as they moved.
