Ezekiel 1:14-16

Revised Standard Version Catholic Edition

¹⁴ And the living creatures darted to and fro, like a flash of lightning.

¹⁵ Now as I looked at the living creatures, I saw a wheel upon 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 a chrysolite; and the four had the same likeness, their construction being as it were a wheel within a wheel.
