'Wheel' in the Bible

Then I looked, and I saw one wheel on the ground beside each of the four beings.

The appearance of the wheels and their construction was like gleaming jasper, and all four wheels looked alike. Their structure was like a wheel within a wheel.

Wherever the spirit would go, they would go, and the wheels would rise up beside them because the spirit of the living being was in the wheel.

When the living beings moved, the wheels moved, and when they stopped moving, the wheels stopped. When they rose up from the ground, the wheels rose up from the ground; the wheels rose up beside them because the spirit of the living being was in the wheel.

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.
