The angel turned back to Abraham. "Know from this moment that the Eternal One has chosen you. Be of good courage and use this authority, as far as I bid you, against him who slanders truth."
Then Iaoel put words of power into Abraham's mouth, words meant to condemn Azazel to his fate:
"Say to him: 'Be the burning coal of the Furnace of the earth! Go, Azazel, into the inaccessible parts of the earth! Your heritage is over those who exist with you, those born with the stars and clouds, the men whose portion you are, and who through your being exist. Your enmity is your own justification. By your perdition, disappear from me.'"
Abraham spoke the words exactly as the angel had taught him. The sentence was absolute. Azazel was not merely banished. He was condemned to be the fire of punishment itself, carrying the furnace of the underworld wherever he went. A walking prison of flame.
But Azazel did not leave quietly. He kept speaking, kept trying to engage Abraham in conversation. The angel warned: "Answer him not, for God has given him power over those who answer him. However much he speaks to you, do not respond, so that his will may have no course in you."
Abraham obeyed. However much Azazel spoke, Abraham answered nothing whatsoever.
Silence was the weapon. The fallen angel's power depended on dialogue, on getting a response, on drawing the righteous into conversation. Abraham shut the door. He said not a single word. And Azazel's voice faded into nothing.
