Matthew 13:10-17

10And the disciples came, and said unto him, Why speakest thou unto them in parables? 11And he answered and said unto them, Unto you it is given to know the mysteries of the kingdom of heaven, but to them it is not given. 12For whosoever hath, to him shall be given, and he shall have abundance: but whosoever hath not, from him shall be taken away even that which he hath. 13Therefore speak I to them in parables; because seeing they see not, and hearing they hear not, neither do they understand. 14And unto them is fulfilled the prophecy of Isaiah, which saith,

16But blessed are your eyes, for they see; and your ears, for they hear. 17For verily I say unto you, that many prophets and righteous men desired to see the things which ye see, and saw them not; and to hear the things which ye hear, and heard them not.
