1 Kings 7:13-15

And king Solomon sent and fetched Hiram out of Tyre. He was a widow's son of the tribe of Naphtali, and his father was a man of Tyre, a worker in brass: and he was filled with wisdom, and understanding, and cunning to work all works in brass. And he came to king Solomon, and wrought all his work. For he cast two pillars of brass, of eighteen cubits high apiece: and a line of twelve cubits did compass either of them about.
