Isaiah 44:12

The smith with the tongs both worketh in the coals and fashioneth it with hammers, rather, in the impersonal form of the original, "One fashioneth iron with the cold-chisel, and causeth it to glow in coals, and with hammers formeth it," and worketh it with the strength of his arms; yea, he is hungry, and his strength falleth; he drinketh no water and is faint. He is so busily engaged that he neglects even eating and drinking, until he becomes utterly exhausted. A similar energy is shown in the case of wooden idols.
