1 Kings 7:13-15

And King Solomon sent and brought Hiram from Tyre. He was the son of a widow of the tribe of Naphtali, and his father was a man of Tyre, a worker in bronze. And he was full of wisdom, understanding, and skill for making any work in bronze. He came to King Solomon and did all his work. 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.
