Isaiah 6:5-10

Then I said, “It’s all over! I am doomed, for I am a sinful man. I have filthy lips, and I live among a people with filthy lips. Yet I have seen the King, the LORD of Heaven’s Armies.” Then one of the seraphim flew to me with a burning coal he had taken from the altar with a pair of tongs. He touched my lips with it and said, “See, this coal has touched your lips. Now your guilt is removed, and your sins are forgiven.” Then I heard the Lord asking, “Whom should I send as a messenger to this people? Who will go for us?” I said, “Here I am. Send me.” And he said, “Yes, go, and say to this people, ‘Listen carefully, but do not understand. Watch closely, but learn nothing.’ Harden the hearts of these people. Plug their ears and shut their eyes. That way, they will not see with their eyes, nor hear with their ears, nor understand with their hearts and turn to me for healing.”
