1 Kings 7:13-15

Now King Solomon sent and brought Hiram from Tyre. He was a widow’s son from the tribe of Naphtali, and his father was a man of Tyre, a worker in bronze; and he was filled with wisdom and understanding and skill for doing any work in bronze. So he came to King Solomon and performed all his work. He fashioned the two pillars of bronze; eighteen cubits was the height of one pillar, and a line of twelve cubits measured the circumference of both.
