John 12:35-40

35 So Jesus said to them, "For a little while longer the Light is among you. Walk while you have the Light, so that darkness will not overtake you; he who walks in the darkness does not know where he goes.

36 "While you have the Light, believe in the Light, so that you may become sons of Light." These things Jesus spoke, and He went away and hid Himself from them.

37 But though He had performed so many signs before them, yet they were not believing in Him.

38 This was to fulfill the word of Isaiah the prophet which he spoke: "LORD , WHO HAS BELIEVED OUR REPORT? AND TO WHOM HAS THE ARM OF THE LORD BEEN REVEALED?"

39 For this reason they could not believe, for Isaiah said again,

40 "HE HAS BLINDED THEIR EYES AND HE HARDENED THEIR HEART, SO THAT THEY WOULD NOT SEE WITH THEIR EYES AND PERCEIVE WITH THEIR HEART, AND BE CONVERTED AND I HEAL THEM"

Mark 6:51-52

51 Then He got into the boat with them, and the wind stopped; and they were utterly astonished,

52 for they had not gained any insight from the incident of the loaves, but their heart was hardened.

Isaiah 6:1-10

1 In the year of King Uzziah's death I saw the Lord sitting on a throne, lofty and exalted, with the train of His robe filling the temple.

2 Seraphim stood above Him, each having six wings: with two he covered his face, and with two he covered his feet, and with two he flew.

3 And one called out to another and said, "Holy, Holy, Holy, is the LORD of hosts, The whole earth is full of His glory."

4 And the foundations of the thresholds trembled at the voice of him who called out, while the temple was filling with smoke.

5 Then I said, "Woe is me, for I am ruined! Because I am a man of unclean lips, And I live among a people of unclean lips; For my eyes have seen the King, the LORD of hosts."

6 Then one of the seraphim flew to me with a burning coal in his hand, which he had taken from the altar with tongs.

7 He touched my mouth with it and said, "Behold, this has touched your lips; and your iniquity is taken away and your sin is forgiven."

8 Then I heard the voice of the Lord , saying, "Whom shall I send, and who will go for Us?" Then I said, "Here am I. Send me!"

9 He said, "Go, and tell this people: 'Keep on listening, but do not perceive; Keep on looking, but do not understand.'

10 "Render the hearts of this people insensitive, Their ears dull, And their eyes dim, Otherwise they might see with their eyes, Hear with their ears, Understand with their hearts, And return and be healed."

Matthew 13:14-15

14 "In their case the prophecy of Isaiah is being fulfilled, which says, 'YOU WILL KEEP ON HEARING, BUT WILL NOT UNDERSTAND; YOU WILL KEEP ON SEEING, BUT WILL NOT PERCEIVE;

15 FOR THE HEART OF THIS PEOPLE HAS BECOME DULL, WITH THEIR EARS THEY SCARCELY HEAR, AND THEY HAVE CLOSED THEIR EYES, OTHERWISE THEY WOULD SEE WITH THEIR EYES, HEAR WITH THEIR EARS, AND UNDERSTAND WITH THEIR HEART AND RETURN, AND I WOULD HEAL THEM.'
