Matthew 13:13-17

Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand. And in them is fulfilled the prophecy of Esaias, which saith, By hearing ye shall hear, and shall not understand; And seeing ye shall see, and shall not perceive: For this people's heart is waxed gross, And their ears are dull of hearing, And their eyes they have closed; Lest at any time they should see with their eyes, And hear with their ears, And should understand with their heart, And should be converted, and I should heal them. But blessed are your eyes, for they see: and your ears, for they hear. For verily I say unto you, That many prophets and righteous men have desired to see those things which ye see, and have not seen them; and to hear those things which ye hear, and have not heard them.
