1 Kings 7:13-15

Now King Solomon sent word and brought Hiram [a skilled craftsman] from Tyre. He was the son of a widow from the tribe of Naphtali, and his father was a man of Tyre, a craftsman in bronze. Hiram was filled with wisdom, understanding, and skill for doing any [kind of] work in bronze. So he came to King Solomon and did all his [bronze] work. He cast the two pillars of bronze; the one pillar was eighteen cubits high, and a [measuring] line of twelve cubits measured the circumference of both.
