Book of Enoch 67:4–11

⁴ And He will imprison those angels, who have shown unrighteousness, in that burning valley which my grandfather Enoch had formerly shown to me in the west among the mountains of gold and silver and iron and soft metal and tin. (ENO) ⁵ And I saw that valley in which there was a great convulsion and a convulsion of the waters. (ENO) ⁶ And when all this took place, from that fiery molten metal and from the convulsion thereof in that place, there was produced a smell of sulphur, and it was connected with those waters, and that valley of the angels who had led astray (mankind) burned beneath that land. (ENO) ⁷ And through its valleys proceed streams of fire, where these angels are punished who had led astray those who dwell upon the earth. (ENO) ⁸ But those waters shall in those days serve for the kings and the mighty and the exalted, and those who dwell on the earth, for the healing of the body, but for the punishment of the spirit; now their spirit is full of lust, that they may be punished in their body, for they have denied the Lord of Spirits and see their punishment daily, and yet believe not in His name. (ENO) ⁹ And in proportion as the burning of their bodies becomes severe, a corresponding change shall take place in their spirit for ever and ever; for before the Lord of Spirits none shall utter an idle word. (ENO) ¹⁰ For the judgement shall come upon them, because they believe in the lust of their body and deny the Spirit of the Lord. (ENO) ¹¹ And those same waters will undergo a change in those days; for when those angels are punished in these waters, these water-springs shall change their temperature, and when the angels ascend, this water of the springs shall change and become cold. (ENO)
