'Refiner' in the Bible

The graven image poured out hath a artisan, And a refiner with gold spreadeth it over, And chains of silver he is refining.

And strengthen doth an artisan the refiner, A smoother with a hammer, Him who is beating on an anvil, Saying, 'For joining it is good,' And he strengtheneth it with nails, it is not moved!

-- They are pouring out gold from a bag, And silver on the beam they weigh, They hire a refiner, and he maketh it a god, They fall down, yea, they bow themselves.
