KJV:
The smith with the tongs both worketh in the coals, and fashioneth it with hammers, and worketh it with the strength of his arms: yea, he is hungry, and his strength faileth: he drinketh no water, and is faint.
NASB:
The man shapes iron into a cutting tool and does his work over the coals, fashioning it with hammers and working it with his strong arm. He also gets hungry and his strength fails; he drinks no water and becomes weary.
