And He said, Go, and tell this people, You listen to hear, but do not understand; you look to see, but do not perceive.

Make the heart of this people fat, and make their ears heavy, and shut their eyes; lest they see with their eyes, and hear with their ears, and understand with their hearts, and turn back, and be healed.

Son of man, you dwell in the midst of a rebellious house, which have eyes to see but do not see, and ears to hear but do not hear; for they are a rebellious house.

so that seeing they may see and not perceive, and hearing they may hear and not understand; lest they should convert, and their sins be forgiven them.

And He said, To you it has been given to know the mysteries of the kingdom of God, but to the rest in parables, that seeing they may not see, and hearing they may not understand.

Therefore they were not able to believe, because Isaiah said again:

He has blinded their eyes and hardened their hearts, that they should not see with their eyes, that they should not understand with their hearts and be turned, and I should heal them.

So when they did not agree among themselves, they were dismissed after Paul had said one word: The Holy Spirit spoke rightly through Isaiah the prophet to our fathers,

for the heart of this people has grown dull. Their ears are hard of hearing, and their eyes they have closed, that they should not see with their eyes nor hear with their ears, that they should not understand with their hearts and turn, and I should heal them.

Just as it is written: God has given them a spirit of deep sleep, eyes that they should not see and ears that they should not hear, to this very day.

Let their eyes be darkened, so that they do not see, and bow down their back always.

But their minds were blinded. For until this day the same veil remains unlifted in the reading of the Old Covenant, which is being done away in Christ.
