'Wheel' in the Bible

When I looked at the living creatures, there was one wheel on the ground beside each creature that had four faces.

The appearance of the wheels and their craftsmanship was like the gleam of beryl, and all four had the same form. Their appearance and craftsmanship was like a wheel within a wheel.

After the Lord commanded the man clothed in linen, saying, “Take fire from inside the wheelwork, from among the cherubim,” the man went in and stood beside a wheel.

I 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.

In appearance, all four had the same form, like a wheel within a wheel.
