1 Kings 7:31-34

31And the mouth of it within the crown and above was a cubit; and its mouth was rounded, [as] the work of the base, a cubit and a half; and also upon its mouth was sculpture; but their panels were square, not round.

32And the four wheels were under the panels; and the supports of the wheels were in the base; and the height of a wheel was a cubit and half a cubit.

33And the work of the wheels was like the work of a chariot wheel: their supports, and their rims, and their spokes and their naves were all molten.

34And there were four shoulder-pieces to the four corners of one base; of the base itself were its shoulder-pieces.
