'Wheel' in the Bible

As I observed the living beings, I noticed one wheel on the earth beside each being that is, for the four of them.

Their wheels and their construction details looked like gold-colored beryl. Each wheel was identical in form to the others, and they appeared to have been constructed and designed as if one wheel were within another.

Their wheel rims were ornate and terrifying. They were full of eyes that surrounded the four of them.

As I continued to watch, I observed four wheels beside the cherubim, one wheel beside each cherub. The wheels resembled beryl stone.

In appearance, the four wheels looked like they consisted of a wheel within a wheel.
