Ezekiel 10:9-13

And then I saw four wheels beside the cherubim, one beside each cherub. The wheels radiating were sparkling like diamonds in the sun. All four wheels looked alike, each like a wheel within a wheel. When they moved, they went in any of the four directions but in a perfectly straight line. Where the cherubim went, the wheels went straight ahead. The cherubim were full of eyes in their backs, hands, and wings. The wheels likewise were full of eyes. I heard the wheels called “wheels within wheels.”
