'Iron smith' in the Bible

The Smith comforted the molder, and the Ironsmith the hammer man, saying, 'It shall be good, that we fasten this cast work,' and then they fastened it with nails, that it should not be moved.

The iron-smith hath a chisel, and he worketh in the coals, and he fashioneth it with hammers, and worketh it with his strong arm; but he is hungry, and his strength faileth; he hath not drunk water, and he is faint.
