2 Chronicles 4:12

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 discernment and knowledge to do any work in bronze. So he came to King Solomon and did all his work.

And 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.

Also from Tibhath and from Cun, cities of Hadadezer, David took a very large amount of bronze, with which Solomon made the bronze sea and the pillars and the bronze utensils.
