Matthew 13:10-15

And the disciples came, and said unto him, Why speakest thou unto them in parables? And 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. For 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. Therefore speak I to them in parables; because seeing they see not, and hearing they hear not, neither do they understand. And unto them is fulfilled the prophecy of Isaiah, which saith, By hearing ye shall hear, and shall in no wise understand; And seeing ye shall see, and shall in no wise perceive: For this people’s heart is waxed gross, And their ears are dull of hearing, And their eyes they have closed; Lest haply they should perceive with their eyes, And hear with their ears, And understand with their heart, And should turn again, And I should heal them.
