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.
Say to those who have an anxious heart, “Be strong; fear not! Behold, your God will come with vengeance, with the recompense of God. He will come and save you.”
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.
