The wheels worked like chariot wheels in that their axles and rims and spokes and hubs were all cast metal.
Underneath the panels were four wheels, and the axles of the wheels were joined to the stand, and the height of a wheel was one cubit and a half.
There were four supports for the four corners of each stand, and the supports were part of one piece with the stand itself.
The appearance of the wheels and their work was like the color of sparkling beryl. And all four of them had one likeness. And their appearance and their work was, as it were, a wheel in the middle of a wheel.
As for their rims, they were so high that they were dreadful. And the rims of all four of them were full of eyes all around.
