"1. And it came to pass when the children of men had multiplied that in those days were born unto them beautiful and comely daughters. 2. And the angels, the children of the heaven, saw and lusted after them, and said to one another: 'Come, let us choose us wives from among the children of men and beget us children.' 3. And Semjâzâ, who was their leader, said unto them: 'I fear ye will not indeed agree to do this deed, and I alone shall have to pay the penalty of a great sin.' 4. And they all answered him and said: 'Let us all swear an oath, and all bind ourselves by mutual imprecations not to abandon this plan but to do this thing.' 5. Then sware they all together and bound themselves by mutual imprecations upon it. 6. And they were in all two hundred; who descended ⌈in the days⌉ of Jared on the summit of Mount Hermon, and they called it Mount Hermon, because they had sworn and bound themselves by mutual imprecations upon it. 7. And these are the names of their leaders: Sêmîazâz, their leader, Arâkîba, Râmêêl, Kôkabîêl, Tâmîêl, Râmîêl, Dânêl, Êzêqêêl, Barâqîjâl, Asâêl, Armârôs, Batârêl, Anânêl, Zaqîêl, Samsâpêêl, Satarêl, Tûrêl, Jômjâêl, Sariêl. 8. These are their chiefs of tens."- Enoch 6 (R.H. Charles translation, 1917)
The sin of the Watchers was that they sought to marry human women, and through them to raise up their own nations in imitation of the Creator. Behind this is jealousy and a lust for experiences of the flesh and power. Their sin led to the Flood, wherein all life on earth but a few were destroyed by God. Interestingly, the Hebrew root word for Hermon means, "devote to destruction".
Many of the early Church Fathers accepted this history given in Enoch as consistent with the canon of Scripture. For example, the following:
"However, those who were born (from the Watchers)- because they were neither angels or human, but had a mixed nature- were not admitted into Hades (when they died)...Thus, there came to be two kinds of demons: one of heaven, the other of the earth. The latter are the wicked spirits, who are the authors of all the evils that are done."- Lactantius
It is easy to see why 1st century Jews and Christians would have given three answers for the origin of evil in the cosmos. They saw the answer(s) being:
- The Fall (Genesis 3)
- The Watchers (Genesis 6:1-4)
- The Judgment at Babel (Genesis 11; Deut. 32:8-9)
