I Kings 7:13-15

Now King Solomon sent and brought Huram from Tyre. He was the son of a widow from the tribe of Naphtali, and his father was a man of Tyre, a bronze worker; he was filled with wisdom and understanding and skill in working with all kinds of bronze work. So he came to King Solomon and did all his work. And he cast two pillars of bronze, each one eighteen cubits high, and a line of twelve cubits measured the circumference of each.
