And in the top of the base was there a round compass of half
a cubit high
The same with the chapiter, ( 1 Kings 7:31 ) which rose up straight half a cubit, and widening upwards half a cubit more, here called the round compass of it:
and on the top of the base, the ledges thereof and the borders thereof,
were of the same;
of the same piece of brass with the base, all being cast together.
