'Wheel' in the Bible

Now as I beheld the living creatures, behold one wheel upon the earth by the living creatures, with his four faces.

The appearance of the wheels and their work was like unto the colour of a beryl: and they four had one likeness: and their appearance and their work was as it were a wheel in the middle of a wheel.

And when I looked, behold the four wheels by the cherubims, one wheel by one cherub, and another wheel by another cherub: and the appearance of the wheels was as the colour of a beryl stone.

And as for their appearances, they four had one likeness, as if a wheel had been in the midst of a wheel.

As for the wheels, it was cried unto them in my hearing, O wheel.
