Ezekiel 10:9-12

9I looked, and each of the four cherubim had a wheel beside him, and the wheels sparkled like beryl.

10All four wheels looked alike and were made the same; each wheel had a second wheel turning crosswise within it.

11The cherubim could move in any of the four directions they faced, without turning as they moved. They went straight in the direction they faced, never turning aside.

12Both the cherubim and the wheels were covered with eyes. The cherubim had eyes all over their bodies, including their hands, their backs, and their wings.
