'Metal worker' in the Bible

So he gave the silver back to his mother. Then his mother took two hundred shekels of silver and gave them to a metal-worker who made a pictured image and a metal image from them: and it was in the house of Micah.

So the metal-worker put heart into the gold-worker, and he who was hammering the metal smooth said kind words to the iron-worker, saying of the plate, It is ready: and he put it together with nails, so that there might be no slipping.
