1 Enoch 99:6
4 In those days the nations shall be stirred up, and the families of the nations shall rise on the day of destruction. 5 And in those days the impoverished shall go forth and carry off their children, and they shall abandon them, so that their children shall perish through them: Yes, they shall abandon their suckling children and not return to them, and shall have no pity on their loved ones. 6 And again I swear to you, sinners, that sin is prepared for a day of unceasing bloodshed. 7 And those who worship stones, and grave images of gold, silver, wood, stone, and clay, and those who worship impure spirits and demons, and all kinds of idols not according to knowledge, shall receive no help from them. 8 And they shall become godless by reason of the folly of their hearts, and their eyes shall be blinded through the fear of their hearts and through visions in their dreams.
Tertullian On Idolatry 4
Enoch had preceded, predicting that the demons, and the spirits of the angelic apostates, would turn into idolatry all the elements, all the garniture of the universe, all things contained in the heaven, in the sea, in the earth, that they might be consecrated as God, in opposition to God. All things, therefore, does human error worship, except the Founder of all Himself. The images of those things are idols; the consecration of the images is idolatry. Whatever guilt idolatry incurs, must necessarily be imputed to every artificer of every idol. In short, the same Enoch fore-condemns in general menace both idol-worshippers and idol-makers together. And again: I swear to you, sinners, that against the day of perdition of blood repentance is being prepared. You who serve stones, and you who make images of gold, and silver, and wood, and stones and clay, and serve phantoms, and demons, and spirits in fanes, and all errors not according to knowledge, shall find no help from them. But Isaiah says, You are witnesses whether there is a God except Me.
Notes and References
"... Tertullian has several references to the teaching of the fallen angels, some closely dependent on 1 Enoch chapters 7-8, and chapter 36, as in "On Women's Apparel" book 1, chapter 2; book 2, chapter 10, where the details of the magic arts, metallurgy, and especially the arts of female adornment are culled from the Greek version of 1 Enoch chapters 7-8. Astrology is also mentioned in "On Women's Apparel" book 1, chapter 2; "On Idolatry" chapter 9. But, like Irenaeus, Tertullian also attributes idolatry to the fallen angels, or rather, revealing his dependence on 1 Enoch chapter 19, verse 1, to "the demons and the spirits of the angelic apostates" ("On Idolatry" chapter 4; compare chapter 3; and also compare "The Apology" chapter 22 on the demonic offspring of the fallen angels as the source of both diseases and pagan religious healings) ..."
