Isaiah 6:8-10

Then I heard the Lord’s voice, saying, “Whom can I send? Who will go for us?” So I said, “Here I am. Send me!” Then the Lord said, “Go and tell this to the people: ‘You will listen and listen, but you will not understand. You will look and look, but you will not learn.’ Make the minds of these people dumb. Shut their ears. Cover their eyes. Otherwise, they might really understand what they see with their eyes and hear with their ears. They might really understand in their minds and come back to me and be healed.”
