Matthew 13:13-16

13 Therefore I speak to them in parables, because seeing they don't see, and hearing, they don't hear, neither do they understand.  14 In them the prophecy of Isaiah is fulfilled, which says,   'By hearing you will hear,  And will in no way understand;  Seeing you will see,  And will in no way perceive:

15 For this people's heart has grown callous,  Their ears are dull of hearing,  They have closed their eyes;  Or else perhaps they might perceive with their eyes,  Hear with their ears,  Understand with their heart,  And should turn again;  And I would heal them.'

16 “But blessed are your eyes, for they see; and your ears, for they hear.
