Isaiah 6:8-10

8Then I heard the voice of the Lord, saying, “Whom will I send? Who will go for us?” I said, “Here I am. Send me!”

9And he said, “Go and tell these people, ‘No matter how closely you listen, you’ll never understand. No matter how closely you look, you’ll never see.’

10Make these people close-minded. Plug their ears. Shut their eyes. Otherwise, they may see with their eyes, hear with their ears, understand with their minds, and return and be healed.”
