Ezekiel 10:9-14

Then I looked, and behold, four wheels beside the cherubim, one wheel beside each cherub; and the appearance of the wheels was like the gleam of a Tarshish stone. As for their appearance, all four of them had the same likeness, as if one wheel were within another wheel. When they moved, they went in any of their four directions without turning as they went; but they followed in the direction which they faced, without turning as they went. Their whole body, their backs, their hands, their wings and the wheels were full of eyes all around, the wheels belonging to all four of them. The wheels were called in my hearing, the whirling wheels. And each one had four faces. The first face was the face of a cherub, the second face was the face of a man, the third the face of a lion, and the fourth the face of an eagle.
