Matthew 13:16

13 Therefore I speak to them in parables: because they seeing see not; and hearing they hear not, neither do they understand.

14 And in them is fulfilled the prophecy of Isaiah, which saith, By hearing ye shall hear, and shall not understand; and seeing ye shall see, and shall not perceive:

15 For this people's heart is become 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.

16 But blessed [are] your eyes, for they see: and your ears, for they hear.

17 For verily I say to you, That many prophets and righteous [men] have desired to see [the things] which ye see, and have not seen [them]; and to hear [the things] which ye hear, and have not heard [them].

18 Hear ye therefore the parable of the sower.

19 When any one heareth the word of the kingdom, and understandeth [it] not, then cometh the wicked [one], and catcheth away that which was sown in his heart. This is he who received seed by the way side.
