1 Kings 7:15

And this work of the bases [was] formed with a border to them, and [there was] a border between the ledges.

And he cast the two pillars for the porch of the house: eighteen cubits [was] the height of [each] pillar, and a circumference of fourteen cubits encompassed it, even the thickness of the pillar: the flutings [were] four fingers [wide], and thus [was] the other pillar [formed].

For he cast two pillars of brass, of eighteen cubits high apiece: and a line of twelve cubits did compass either of them about.
