Cherubim » Engaged in accomplishing the purposes of God
Then I looked, and I saw one wheel on the ground beside each of the four beings.
As I watched, I noticed four wheels by the cherubim, one wheel beside each cherub; the wheels gleamed like jasper. As for their appearance, all four of them looked the same, something like a wheel within a wheel. When they moved, they would go in any of the four directions they faced without turning as they moved; in the direction the head would turn they would follow without turning as they moved,
When the cherubim moved, the wheels moved beside them; when the cherubim spread their wings to rise from the ground, the wheels did not move from their side. When the cherubim stood still, the wheels stood still, and when they rose up, the wheels rose up with them, for the spirit of the living beings was in the wheels.
