4 At the sound of that cry, the frame of the door shook and the house was filled with smoke.
5 Then I said, “Woe is me, I am doomed! For I am a man of unclean lips, living among a people of unclean lips, and my eyes have seen the King, the Lord of hosts!”
6 Then one of the seraphim flew to me, holding an ember which he had taken with tongs from the altar.
7 He touched my mouth with it. “See,” he said, “now that this has touched your lips, your wickedness is removed, your sin purged.”
8 Then I heard the voice of the Lord saying, “Whom shall I send? Who will go for us?” “Here I am,” I said; “send me!”
9 And he replied: Go and say to this people:Listen carefully, but do not understand!Look intently, but do not perceive!
10 Make the heart of this people sluggish,dull their ears and close their eyes;Lest they see with their eyes, and hear with their ears,and their heart understand,and they turn and be healed.
