1 Kings 7:33-35

New King James Version

³³ The workmanship of the wheels was like the workmanship of a chariot wheel; their axle pins, their rims, their spokes, and their hubs were all of cast bronze. ³⁴ And there were four supports at the four corners of each cart; its supports were part of the cart itself. ³⁵ On the top of the cart, at the height of half a cubit, it was perfectly round. And on the top of the cart, its flanges and its panels were of the same casting.
