You shall hear indeed, but you shall not understand; and you shall see indeed, but you shall not perceive.

For the heart of this people has become dull, and their ears are hard of hearing, and they have closed their eyes; lest they should see with their eyes, and hear with their ears, and understand with their heart, and be converted, and I should heal them.

Son of man, you dwell in the midst of the iniquities of those who have eyes to see, and see not; and have ears to hear, and hear not; because they are a provoking house.

And in them is fulfilled the prophecy of Isaiah, which says: 'Hearing you shall hear and by no means understand, and seeing you shall see and by no means perceive.

For the heart of this people has become dull, and their ears are hard of hearing, and their eyes have closed, lest they should see with their eyes, and hear with their ears, lest they should understand with their hearts and turn back, that I should heal them.'

so that 'Seeing they may see and not perceive, and hearing they may hear and not understand; Lest they should turn, 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 [they are] in parables, that 'Seeing they may not see, and hearing they may not understand.'

that the word of Isaiah the prophet might be fulfilled, which he said: "Lord, who has believed our report? And to whom has the arm of the LORD been revealed?"

"He has blinded their eyes and hardened their hearts, lest they should see with their eyes, lest they should understand with their hearts and turn, and I would heal them."

Just as it is written: "God has given them a spirit of stupor, 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 their back always be bowed down."

Yet the Lord God has not given you a heart to know, and eyes to see, and ears to hear, until this day.

But My people hearkened not to My voice; and Israel gave no heed to Me.

So I let them go after the ways of their own hearts; they will go on in their own ways.

For the Lord has made you to drink a spirit of deep sleep; and He shall close their eyes, and [the eyes] of their prophets and of their rulers, who see secret things.

Therefore behold, I will proceed to remove this people, and I will remove them; and I will destroy the wisdom of the wise, and will hide the understanding of the prudent.

And who is blind, but My servants? And [who is] deaf, but those that rule over them? Yes, the servants of God have been made blind.

You have often seen, and have not taken heed; [your] ears have been opened, and you have not heard.

I also will choose their mockeries, and will recompense their sins upon them; because I called them, and they did not hearken to Me; I spoke, and they heard not; and they did evil before Me, and chose the things in which I did not delight.

Hear now these things, O foolish and senseless people; who have eyes, and see not; and have ears, and hear not:

neither to many nations of other speech and other tongues, nor of harsh language, whose words you would not understand; although if I [had] sent you to such, they would have hearkened to you.

But the house of Israel will not be willing to hearken to you; for they will not hearken to Me; for all the house of Israel are stubborn and hard-hearted.

Son of man, you dwell in the midst of the iniquities of those who have eyes to see, and see not; and have ears to hear, and hear not; because they are a provoking house.

But Jesus, knowing about it, said to them, "Why are you reasoning because you have no bread? Do you not yet perceive or understand? Is your heart still hardened?

Having eyes, do you not see? And having ears, do you not hear? And do you not remember?

Then He said to them, "O [you] foolish, and slow of heart to believe in all that the prophets have spoken!

And He opened their understanding, that they might comprehend the Scriptures.

among whom the god of this age has blinded the minds of the unbelievers, so that the illumination of the gospel of the glory of Christ, who is the image of God, should not shine on them.

Because it is God who commanded light to shine out of darkness, who shined in our hearts to give [the] light of the knowledge of the glory of God in [the] face of Jesus Christ.
