19 Now there was no blacksmith to be found throughout all the land of Israel, for the Philistines said, “Lest the Hebrews make themselves swords or spears.”
Isaiah 41
7 The craftsman strengthens the goldsmith, and he who smooths with the hammer him who strikes the anvil, saying of the soldering, “It is good”; and they strengthen it with nails so that it cannot be moved.
Isaiah 44
12 The ironsmith takes a cutting tool and works it over the coals. He fashions it with hammers and works it with his strong arm. He becomes hungry, and his strength fails; he drinks no water and is faint.
