Apocalypse of Abraham 14:1-14

1 And the angel said to me, "Abraham!" And I said, "Here I am, your 2 servant." And he said, "Know from this that the Eternal One whom you have 3 loved has chosen you. Be bold and do through your authority whatever I order 4 you against him who reviles justice. Will I not be able to revile him who has scattered about the earth the secrets of heaven and who has taken counsel against 5 the Mighty One? Say to him, ‘May you be the firebrand of the furnace of the 6 earth! Go, Azazel, into the untrodden parts of the earth. For your heritage is over those who are with you, with the stars and with the men born by the clouds, 7 whose portion you are, indeed they exist through your being. Enmity is for you 8 a pious act. Therefore through your own destruction be gone from me!’

9 And I said the words as the angel had taught me. And he said, "Abraham." And I 10 said, "Here I am, your servant!" And the angel said to me, "Answer him not!" 11 And he spoke to me a second time. And the angel said, "Now, whatever he says to you, answer him not, lest his will run up to you. For the Eternal, Mighty 14 One gave him the gravity and the will. Answer him not." And I did what the angel had commanded me. And whatever he said to me about the descent, I answered him not.

Rabbinic

The Gemara asks: And the other, what does he do with this word gezeira? The Gemara answers: He needs it for that which was taught in a baraita with regard to the word gezeira: Gezeira means nothing other than cut. That is, he must send the goat away to a place cut up by rocks standing upright and sticking out. Alternatively, gezeira is referring to nothing other than something that breaks apart and falls, a reference to the goat, which is torn limb from limb.

Alternatively, the word gezeira is written lest you say the procedure of the scapegoat is a meaningless act, since what sanctity and atonement is achieved in sending the goat to Azazel and pushing it from the cliff? Therefore, the verse states: “I am the Lord”, i.e., I, the Lord, decreed it [gezartiv], and you have no right to question it.

... The school of Rabbi Yishmael taught: Azazel is so called because it atones for the actions of Uzza and Azael. These are the names of “sons of God” who sinned with “daughters of men” and thereby caused the world to sin during the generation of the Flood.
