Isaiah 6:9-10

KJV_Cambridge(i) 10 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. 9 And he said, Go, and tell this people, Hear ye indeed, but understand not; and see ye indeed, but perceive not.
