Jews were blinded

Daniel 9:24 24 “ Seventy weeks are determined For your people and for your holy city, To finish the transgression, To make an end of sins, To make reconciliation for iniquity,To bring in everlasting righteousness, To seal up vision and prophecy, And to anoint the Most Holy.
(Romans 11:10) Let their eyes be darkened, so that they do not see,
And bow down their back always.”

Matthew 13:10-17 The Purpose of Parables
And the disciples came and said to Him, “Why do You speak to them in parables?”
  He answered and said to them, “Because it has been given to you to know the mysteries of the kingdom of heaven, but to them it has not been given. 1For whoever has, to him more will be given, and he will have abundance; but whoever does not have, even what he has will be taken away from him. Therefore I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand. And in them the prophecy of Isaiah is fulfilled, which says: ‘ Hearing you will hear and shall not understand, And seeing you will see and not perceive 
For the hearts of this people have grown dull. Their ears are hard of hearing, And their eyes they have closed, Lest they should see with their eyes and hear with their ears, Lest they should understand with their hearts and turn, So that I should heal them.’
 But blessed are your eyes for they see, and your ears for they hear, for assuredly, I say to you that many prophets and righteous men desired to see what you see, and did not see it, and to hear what you hear, and did not hear it.

Luke 19:41-42 Jesus Weeps over Jerusalem
Now as He drew near, He saw the city and wept over it, 42 saying, “If you had known, even you, especially in this your day, the things that make for your peace! But now they are hidden from your eyes.

John 9:39-41
And Jesus said, “For judgment I have come into this world, that those who do not see may see, and that those who see may be made blind.”  Then some of the Pharisees who were with Him heard these words, and said to Him, “Are we blind also?”
Jesus said to them, “If you were blind, you would have no sin, but now you say, ‘We see.’ Therefore your sin remains.

John 9:39
  And Jesus said, “For judgment I have come into this world, that those who do not see may see, and that those who see may be made blind.”

Isaiah 42:18-19 
“ Hear, you deaf; And look, you blind, that you may see.Who is blind but My servant, Or deaf as My messenger whom I send?
Who is blind as he who is perfect, And blind as the LORD’s servant?

John 9:41
Jesus said to them, “If you were blind, you would have no sin; but now you say, ‘We see.’ Therefore your sin remains.

John 15:22-24
If I had not come and spoken to them, they would have no sin, but now they have no excuse for their sin. 23 He who hates Me hates My Father also. 24 If I had not done among them the works which no one else did, they would have no sin; but now they have seen and also hated both Me and My Father.

2 Corinthians 3:14-16 
 But their minds were blinded. For until this day the same veil remains unlifted in the reading of the Old Testament, because the veil is taken away in Christ. 15 But even to this day, when Moses is read, a veil lies on their heart. 
Nevertheless when one turns to the Lord, the veil is taken away.
