1 Kings 7:31-34
7:31 Inside the stand was a round opening that was a foot-and-a-half deep; it had a support that was two and one-quarter feet long. On the edge of the opening were carvings in square frames.
7:32 The four wheels were under the frames and the crossbars of the axles were connected to the stand. Each wheel was two and one-quarter feet high.
7:33 The wheels were constructed like chariot wheels; their crossbars, rims, spokes, and hubs were made of cast metal.
7:34 Each stand had four supports, one per side projecting out from the stand.
