Also I heard the voice of the Lord, saying, "Whom shall I send, and who will go for us?" Then said I, "Here am I; send me." And he said, "Go, and tell this people, Hear ye indeed, but understand not; and see ye indeed, but percieve not. Make the heart of this people fat, and make their ears heavy, and shut their eyes; lest they see with their eyes, and hear with their ears, and understand with their heart, and convert, and be healed." Isaiah 6: 8~10
