Matthew 13:15-16

For this nation's heart has grown gross (fat and dull), and their ears heavy and difficult of hearing, and their eyes they have tightly closed, lest they see and perceive with their eyes, and hear and comprehend the sense with their ears, and grasp and understand with their heart, and turn and I should heal them. [Isa. 6:9, 10.] But blessed (happy, fortunate, and to be envied) are your eyes because they do see, and your ears because they do hear.
