1 Enoch 9:6

1 And then Michael, Uriel, Raphael, and Gabriel looked down from heaven and saw much blood being shed upon the earth, and all lawlessness being wrought upon the earth. 2 And they said one to another: 'The earth made †without inhabitant cries the voice of their crying† up to the gates of heaven. 3 ⌈⌈And now to you, the holy ones of heaven⌉⌉, the souls of men make their suit, saying, "Bring our cause before the Most High.".' 4 And they said to the Lord of the ages: 'Lord of lords, God of gods, King of kings, 〈and God of the ages〉, the throne of Thy glory (standeth) unto all the generations of the ages, and Thy name holy and glorious and blessed unto all the ages! 5 Thou hast made all things, and power over all things hast Thou: and all things are naked and open in Thy sight, and Thou seest all things, and nothing can hide itself from Thee. 6 Thou seest what Azâzêl hath done, who hath taught all unrighteousness on earth and revealed the eternal secrets which were (preserved) in heaven, which men were striving to learn: 7 And Semjâzâ, to whom Thou hast given authority to bear rule over his associates. 8 And they have gone to the daughters of men upon the earth, and have slept with the women, and have defiled themselves, and revealed to them all kinds of sins. 9 And the women have borne giants, and the whole earth has thereby been filled with blood and unrighteousness. 10 And now, behold, the souls of those who have died are crying and making their suit to the gates of heaven, and their lamentations have ascended: and cannot cease because of the lawless deeds which are wrought on the earth. 11 And Thou knowest all things before they come to pass, and Thou seest these things and Thou dost suffer them, and Thou dost not say to us what we are to do to them in regard to these.'

Irenaeus Against Heresies 1.15

6 With good reason, therefore, and very fittingly, in reference to your rash attempt, has that divine elder and preacher of the truth burst forth in verse against you as follows: Marcus, you former of idols, inspector of portents, Skill'd in consulting the stars, and deep in the black arts of magic, Ever by tricks such as these confirming the doctrines of error, Furnishing signs unto those involved by you in deception, Wonders of power that is utterly severed from God and apostate, Which Satan, your true father, enables you still to accomplish, By means of Azazel, that fallen and yet mighty angel — Thus making you the precursor of his own impious actions. Such are the words of the saintly elder. And I shall endeavour to state the remainder of their mystical system, which runs out to great length, in brief compass, and to bring to the light what has for a long time been concealed. For in this way such things will become easily susceptible of exposure by all.
