421. What did the Holy One, blessed be He, do? He saw that they, AZA AND AZAEL, were misleading the world. He bound them with chains of iron in the dark mountains. Where are they situated? In the valley of the mountains. He placed Aza there and threw darkness in his face, because when the Holy One, blessed be He, bound them, he strengthened himself to provoke anger to the higher. AS A RESULT, the Holy One, blessed be He, dropped him down to his neck and threw darkness in his face. He placed Azael, who did not strengthen himself, next to Aza and illuminated the darkness for him.
458. Rabbi Elazar said that vayikar MEANS THAT Bilaam believed he would be able to harm Yisrael with that gift. The Holy One, blessed be He, eradicated that gift from His presence, expunged Bilaam from such thoughts and uprooted him from that level. That is what is meant by vayiker, as it says, "The ravens of the valley shall pick it up (Heb. yikruha)" (Mishlei 30:17). He said to him, 'Wicked one, you are not worthy to be associated with Me or to enter into My presence. Your gift will be given to the dog.'
