Isaiah 6:9-10

6:9 He said, “Go and tell these people:

‘Listen continually, but don’t understand!

Look continually, but don’t perceive!’

6:10 Make the hearts of these people calloused;

make their ears deaf and their eyes blind!

Otherwise they might see with their eyes and hear with their ears,

their hearts might understand and they might repent and be healed.”

Isaiah 26:11

26:11 O Lord, you are ready to act,

but they don’t even notice.

They will see and be put to shame by your angry judgment against humankind,

yes, fire will consume your enemies.

Isaiah 29:10-11

29:10 For the Lord has poured out on you

a strong urge to sleep deeply.

He has shut your eyes (the prophets),

and covered your heads (the seers).

29:11 To you this entire prophetic revelation is like words in a sealed scroll. When they hand it to one who can read and say, “Read this,” he responds, “I can’t, because it is sealed.”

Isaiah 42:19-20

42:19 My servant is truly blind,

my messenger is truly deaf.

My covenant partner, the servant of the Lord, is truly blind.

42:20 You see many things, but don’t comprehend;

their ears are open, but do not hear.”

Jeremiah 5:21

5:21 Tell them: ‘Hear this,

you foolish people who have no understanding,

who have eyes but do not discern,

who have ears but do not perceive:

Matthew 13:13-15

13:13 For this reason I speak to them in parables: Although they see they do not see, and although they hear they do not hear nor do they understand. 13:14 And concerning them the prophecy of Isaiah is fulfilled that says:

‘You will listen carefully yet will never understand,

you will look closely yet will never comprehend.

13:15 For the heart of this people has become dull;

they are hard of hearing,

and they have shut their eyes,

so that they would not see with their eyes

and hear with their ears

and understand with their hearts

and turn, and I would heal them.’

John 12:39-40

12:39 For this reason they could not believe, because again Isaiah said,

12:40 “He has blinded their eyes

and hardened their heart,

so that they would not see with their eyes

and understand with their heart,

and turn to me, and I would heal them.”
