1 Kings 7:15

He cast two pillars of bronze . Eighteen cubits was the height of one pillar , and a line of twelve cubits measured its circumference . It was hollow, and its thickness was four fingers. The second pillar was the same.

He cast two bronze pillars, each eighteen cubits high and twelve cubits in circumference.

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