Ezekiel 10:8-10

New Catholic Bible

⁸ The cherubim seemed to have under their wings what appeared to be a human hand.

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.
