'Tongs' in the Bible

Then flew one of the seraphims unto me, having a live coal in his hand, which he had taken with the tongs from off the altar:

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.
