'Worker' in the Bible

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.

Jeroboam was a talented man; when Solomon saw that the young man was an accomplished worker, he made him the leader of the work crew from the tribe of Joseph.
