Chapter 6

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
3 and beget us children.' And Semjaza, who was their leader, said unto them: 'I fear ye will not
4 indeed agree to do this deed, and I alone shall have to pay the penalty of a great sin.' And they all answered him and said: 'Let us all swear an oath, and all bind ourselves by mutual imprecations
5 not to abandon this plan but to do this thing.' Then sware they all together and bound themselves
6 by mutual imprecations upon it. 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
7 and bound themselves by mutual imprecations upon it. And these are the names of their leaders: Samlazaz, their leader, Araklba, Rameel, Kokablel, Tamlel, Ramlel, Danel, Ezeqeel, Baraqijal,
8 Asael, Armaros, Batarel, Ananel, Zaq1el, Samsapeel, Satarel, Turel, Jomjael, Sariel. These are their chiefs of tens.

Chapter 7

1 And all the others together with them took unto themselves wives, and each chose for himself one, and they began to go in unto them and to defile themselves with them, and they taught them charms
2and enchantments, and the cutting of roots, and made them acquainted with plants. And they
3 became pregnant, and they bare great giants, whose height was three thousand ells: Who consumed
4 all the acquisitions of men. And when men could no longer sustain them, the giants turned against
5 them and devoured mankind. And they began to sin against birds, and beasts, and reptiles, and
6 fish, and to devour one another's flesh, and drink the blood. Then the earth laid accusation against the lawless ones.

Chapter 8

1 And Azazel taught men to make swords, and knives, and shields, and breastplates, and made known to them the metals of the earth and the art of working them, and bracelets, and ornaments, and the use of antimony, and the beautifying of the eyelids, and all kinds of costly stones, and all
2 colouring tinctures. And there arose much godlessness, and they committed fornication, and they
3 were led astray, and became corrupt in all their ways. Semjaza taught enchantments, and root-cuttings, 'Armaros the resolving of enchantments, Baraqijal (taught) astrology, Kokabel the constellations, Ezeqeel the knowledge of the clouds, Araqiel the signs of the earth, Shamsiel the signs of the sun, and Sariel the course of the moon. And as men perished, they cried, and their cry went up to heaven . . .
