1 Kings 7:30-34

Now each stand had four bronze wheels with bronze axles, and its four feet had supports; beneath the basin were cast supports with wreaths at each side.

And its opening inside the crown at the top was a cubit, and its opening was round like the design of a pedestal, a cubit and a half; and on its opening also there were engravings, and their borders were square, not round.

The four wheels were underneath the borders, and the axles of the wheels were on the stand. And the height of a wheel was a cubit and a half.

The workmanship of the wheels was like the workmanship of a chariot wheel. Their axles, their rims, their spokes, and their hubs were all cast.

Now there were four supports at the four corners of each stand; its supports were part of the stand itself.
