Ezekiel 10:9-12

9I looked, and there were four wheels beside the cherubim, one wheel beside each cherub. The luster of the wheels was like the gleam of beryl.

10In appearance, all four looked alike, like a wheel within a wheel.

11When they moved, they would go in any of the four directions, without pivoting as they moved. But wherever the head faced, they would go in that direction, without pivoting as they went.

12Their entire bodies, including their backs, hands, wings, and the wheels that the four of them had, were full of eyes all around.
