Isaiah 6:5-8

I said, “Mourn for me; I’m ruined! I’m a man with unclean lips, and I live among a people with unclean lips. Yet I’ve seen the king, the LORD of heavenly forces!” Then one of the winged creatures flew to me, holding a glowing coal that he had taken from the altar with tongs. He touched my mouth and said, “See, this has touched your lips. Your guilt has departed, and your sin is removed.” Then I heard the Lord’s voice saying, “Whom should I send, and who will go for us?” I said, “I’m here; send me.”
