and shall cast them into the furnace of fire; there shall be the weeping and the gnashing of teeth.

and his feet like fine brass, as burning in a furnace; and his voice as the voice of many waters;

And it opened the pit of the abyss; and there went up smoke out of the pit as the smoke of a great furnace; and the sun and the air were darkened with the smoke of the pit.
