1 Kings 7:31-34

31And the mouth of it within the chapiter and above was a cubit: and the mouth thereof was round after the work of a pedestal, a cubit and an half: and also upon the mouth of it were gravings, and their borders were foursquare, not round.

32And the four wheels were underneath the borders; and the axletrees 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 axletrees, and their felloes, and their spokes, and their naves, were all molten.

34And there were four undersetters at the four corners of each base: the undersetters thereof were of the base itself.
