Isaiah 6:5-10

Then I stammered and said, “Woe is me! I’m destroyed —doomed as a sinful man! For my words are tainted and I live among people who talk the same way. King YAHWEH, Commander of Angel Armies—my eyes have gazed upon him!” Then out of the smoke, one of the angels of fire flew to me. He had in his hands a burning coal he had taken from the altar with tongs. He touched my lips with it and said, “See? The burning coal from the altar has touched your lips. Your guilt is taken away; your sin is blotted out.” Then I heard the Lord saying, “Whom should I send to my people? Who will go to represent us?” I spoke up and said, “I will be the one. Send me.” Then he said, “Go and tell the people: ‘You keep listening but understand nothing. You keep watching but learn nothing.’ Go and preach a message that will make their hearts dull, their ears plugged, and their eyes blind. Otherwise, their eyes will begin to see, their ears will begin to hear, their hearts will begin to understand, and they will return to me for healing and be healed.”
