1 Kings 7:31

Its opening within the capital and above was a cubit. Its opening was round like the work of a pedestal, a cubit and a half; and also on its opening were engravings, and their panels were square, not round.

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