The Book of Enoch
The oldest text ever written. Written by Enoch, the seventh from Adam, who walked with God and was taken.
Chapter 1: The Judgment of the Watchers
In those days, and at that time, it shall come to pass that the Most High, the Holy, and Great One shall come forth and appear upon the Mount of Holiness. And all the earth shall tremble before Him, and the high mountains shall be melted as wax before the fire, and they shall be made smooth as a plain. And the hills shall be crumbled as chaff from the threshingfloor, and as foam blown by a mighty wind.
And it shall come to pass that every foot shall be stayed, and every hand shall hang limp. And they shall be afraid, and trembling shall seize them, and it shall be as with a woman in the pains of childbirth. And they shall hide themselves, and one shall not see another; and they shall seek caves and crevices of rocks, and the tops of the mountains, and the cliffs, to which they may flee for refuge from the face of Him whose fury is kindled against all the earth.
Chapter 6: The Descent of the Watchers
And it came to pass when the children of men had multiplied, that in those days were born unto them beautiful and fair daughters. And the angels, the sons of the heaven, saw, and loved them, and went down to the earth, and entered unto them; and they took them unto themselves, and defiled themselves; and they began to teach them enchantments and incantations.
And these are the names of them: The first of them was Semjaza, who was their leader; the second was called Arak; the third, Ramiel; the fourth, Kokabiel; the fifth, Ezequiel; the sixth, Baraqijal; the seventh, Asraquel; the eighth, Aramiel; the ninth, Danel; the tenth, Epenetel; the eleventh, Tamiel; the twelfth, Remiel; the thirteenth, Anael; the fourteenth, Samsapeel; the fifteenth, Satarel; the sixteenth, Turel; the seventeenth, Jomael; the eighteenth, Sariel; the nineteenth, Jerahmeel; the twentieth, Batarel.
Chapter 15: God's Warning
And the Lord said unto the Watchers, the holy ones, who are in heaven, never, for all eternity, let them leave their high heaven, come to the earth, and defile themselves with women, as the others, the first Watchers, did; they transgressed with the daughters of men.
Chapter 69: The Binding of the Watchers
And I saw that all the sons of light, the holy ones, who are in heaven, came to me and said to me: 'This man is he who is born of woman and has been chosen in heaven and on earth; go and bring him.' And I went and brought Enoch, and they led him to the presence of the Lord of Spirits.
And he said to me: 'Bind them hand and foot for seventy generations in the valleys of the earth, until the day of their judgment and of their consummation, until the judgment that is forever comes. And they shall be cast into the prison, and they shall be shut up therein for all ages.'
