Isaiah 6:9

And when he was alone, they that were about him with the twelve asked of him the parable. And he said unto them, Unto you it is given to know the mystery of the kingdom of God: but unto them that are without, all these things are done in parables: That seeing they may see, and not perceive; and hearing they may hear, and not understand; lest at any time they should be converted, and their sins should be forgiven them. [Isaiah 6:9-10] And he said unto them, Know ye not this parable? and how then will ye know all parables?

And the disciples came, and said unto him, Why speakest thou unto them in parables? He answered and said unto them, Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given. For whosoever hath, to him shall be given, and he shall have more abundance: but whosoever hath not, from him shall be taken away even that he hath. Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand. And in them is fulfilled the prophecy of Esaias, which saith, By hearing ye shall hear, and shall not understand; and seeing ye shall see, and shall not perceive: For this people's heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them. [Isaiah 6:9-10] But blessed are your eyes, for they see: and your ears, for they hear. For verily I say unto you, That many prophets and righteous men have desired to see those things which ye see, and have not seen them; and to hear those things which ye hear, and have not heard them.

And his disciples asked him, saying, What might this parable be? And he said, Unto you it is given to know the mysteries of the kingdom of God: but to others in parables; that seeing they might not see, and hearing they might not understand. [Isaiah 6:9-10]

And when they had appointed him a day, there came many to him into his lodging; to whom he expounded and testified the kingdom of God, persuading them concerning Jesus, both out of the law of Moses, and out of the prophets, from morning till evening. And some believed the things which were spoken, and some believed not. And when they agreed not among themselves, they departed, after that Paul had spoken one word, Well spake the Holy Ghost by Esaias the prophet unto our fathers, Saying, Go unto this people, and say, Hearing ye shall hear, and shall not understand; and seeing ye shall see, and not perceive: For the heart of this people is waxed gross, and their ears are dull of hearing, and their eyes have they closed; lest they should see with their eyes, and hear with their ears, and understand with their heart, and should be converted, and I should heal them. [Isaiah 6:9-10] Be it known therefore unto you, that the salvation of God is sent unto the Gentiles, and that they will hear it.

Then Jesus said unto them, Yet a little while is the light with you. Walk while ye have the light, lest darkness come upon you: for he that walketh in darkness knoweth not whither he goeth. While ye have light, believe in the light, that ye may be the children of light. These things spake Jesus, and departed, and did hide himself from them. But though he had done so many miracles before them, yet they believed not on him: That the saying of Esaias the prophet might be fulfilled, which he spake, Lord, who hath believed our report? and to whom hath the arm of the Lord been revealed? Therefore they could not believe, because that Esaias said again, He hath blinded their eyes, and hardened their heart; that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them. [Isaiah 6:9-10] These things said Esaias, when he saw his glory, and spake of him. Nevertheless among the chief rulers also many believed on him; but because of the Pharisees they did not confess him, lest they should be put out of the synagogue: For they loved the praise of men more than the praise of God.

(Verse 9 and following) And he said: Go, and say to this people: Hearing, you shall hear, and shall not understand; and seeing, you shall see, and shall 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 heart, and convert, and be healed. The Septuagint translates this passage as follows, as the evangelist Luke placed it in the Acts of the Apostles: And when they did not agree with one another, it is certain that the Jews departed, as Paul said one word: Because the Holy Spirit has spoken well through Isaiah the prophet to our fathers, saying: Go to this people, and say: Hearing, you shall hear, and shall not understand; and seeing, you shall see, and shall not perceive; for the heart of this people has grown fat, and they have heavily heard with their ears, and have shut their eyes, lest they see with their eyes, and hear with their ears, and understand with their heart, and be converted, and I heal them (Acts 28:25 and following). But as for the time when this prophecy was fulfilled, the Apostle Paul himself speaks in the following words: Therefore let it be known to you that this salvation of God has been sent to the Gentiles; they will listen. (Acts 28:28) Hence, in the same Acts of the Apostles, we read that Paul and Barnabas, when the Jews refused to believe, said: It was necessary that the word of God be spoken first to you. But since you reject it and judge yourselves unworthy of eternal life, behold, we are turning to the Gentiles. (Acts 13:46, 47) For thus the Lord commanded us: I have set you as a light for the Gentiles, that you may be for salvation to the ends of the earth (Isaiah 49:6). Therefore, according to the easy interpretation of the Septuagint, Isaiah the prophet declares what the people will do by the command of the Lord. In Hebrew, there is a difficulty in how God Himself commands the people to hear but not understand, to see but not perceive, and then the prophet comes and prays to the Lord and says: Blind the heart of this people, and make their ears heavy, and shut their eyes; lest they see with their eyes, and hear with their ears, and understand with their heart, and be converted, and be healed (Isaiah 6:10). First of all, the question that can be posed to us must be answered: why did the apostle Paul, when disputing with the Hebrews, speak not according to the Hebrew that he knew to be correct, but according to the Septuagint? The ancient commentators of the Church claim that the evangelist Luke was extremely knowledgeable in the medical arts and had a greater understanding of Greek letters than Hebrew. Hence, his language in both the Gospel and the Acts of the Apostles is more polished and reminiscent of secular eloquence, and he makes greater use of Greek testimonies than Hebrew ones. But Matthew and John, of whom one wrote the Gospel in Hebrew and the other in Greek, cite testimonies from the Hebrew, such as: 'Out of Egypt I have called my Son' (Hosea II, 1). And: 'He shall be called a Nazarene' (Matthew II, 23). And: 'Out of his belly shall flow rivers of living water' (John VII, 38). And: 'They shall look upon him whom they have pierced' (Zechariah XII, 10; John XIX, 37), and others similar to these. Moreover, it can be objected that the Epistle to the Hebrews is not Paul's because in writing to the Hebrews, he uses testimonies that are not found in Hebrew volumes. But if someone were to say that the Hebrew books were later falsified by the Jews, let them hear what Origen responds to this question in the eighth volume of his Explanations of Isaiah, namely that the Lord and the Apostles, who accuse the scribes and Pharisees of other crimes, would not have remained silent about this greatest crime. But if they were to say that the Hebrew books were falsified after the coming of the Lord Savior and the preaching of the Apostles, I cannot help but laugh, because the Savior, the Evangelists, and the Apostles presented their testimonies in such a way that the Jews would later falsify them. However, in the present place, it must be said that it is in vain for us to resort to the Septuagint translation, lest it seem blasphemous that what is said in Hebrew, Hear and you shall not understand, and see the vision, and you shall not know, we also find such testimonies in the Seventy Interpreters, as is the case in Exodus where it is said to Pharaoh: For this very reason have I raised you up, that I may show my power in you. But if he Himself raised up and hardened the heart of Pharaoh, that he should not believe: and of others it is said: God hath given them the spirit of insensibility, eyes that they should not see, and ears that they should not hear (Rom. XI, 8); and in the Psalms: Let their table be made a snare, and a trap, and a stumbling block, and a recompense unto them: let their eyes be darkened that they may not see, and their back bend thou down always (Ps. LXVIII, 23, 24): they are not to be blamed who do not see, but He who gave eyes that they should not see. Therefore, even without this testimony that we are now trying to explain, the same question remains in the churches, and either with these things being resolved along with the others, or with the others being resolved and this one remaining unsolvable. The blessed apostle Paul explains this matter more fully in his letter to the Romans, and what he has almost entirely discussed throughout the letter, we make unnecessary if we wish to summarize it in a short speech. For he says after many things: God has concluded all in unbelief, that he may have mercy upon all (Rom. 11:32). And admiring the sacraments of the Lord, he exclaimed: O the depth of the riches of the wisdom and knowledge of God, how unsearchable are his judgments, and his ways past finding out! And again, speaking about the incredulity of the Jews, he says: Have they then stumbled that they should fall? God forbid; but by their offense salvation is come to the Gentiles, that they may be provoked to emulation. And after a little while: For if the loss of them be the reconciliation of the world, what shall the receiving of them be? Is not life from the dead? And again: I don't want you to be unaware, brothers, of this mystery, so that you may not be wise in your own sight, for a partial hardening has come upon Israel, until the fullness of the Gentiles comes in. And then all Israel will be saved. And in a little while (Rom. XI, 25): According to the Gospel, they are enemies for your sake, but according to election, they are beloved for the sake of the fathers: for the gifts and the calling of God are irrevocable. For just as you, he says, at one time did not believe in God but now have attained mercy due to their disbelief, so too these individuals now have not believed in your mercy, in order that they may also attain mercy. For God has concluded all under sin, so that he may have mercy on all. Therefore, it is not cruelty on God's part, but mercy, for one nation to perish so that all may be saved: that the part of the Jews may not be seen, so that the whole world may be seen. And the Lord Himself in the Gospel turns the miracle of the blind man from birth, who had received his sight, into a Tropology, and He says: 'For judgment I have come into this world, that those who do not see may see, and that those who see may become blind.' (John 9:39). And in another place, Simeon speaks: 'Behold, this child is set for the fall and the rising of many.' (Luke 2:34). Therefore, while they do not see, we see; while they fall, we rise. The Prophet, understanding in a certain way, says in other words: O Lord, you command me to speak to the people of Judah, so that they may hear and not understand the Savior, and see him, and not recognize him. If you want your command to be fulfilled, and the whole world to be saved, which I also desire, blind the heart of this people and make their ears heavy, and close their eyes, so that they may not understand, hear, or see. For if they see, and are converted, and understand, and are healed, the whole world will not receive healing. From this, we understand that although sin is grave, if someone converts, they can be healed. And at the same time, it must be understood that for the magnitude of the crime, they are deemed unworthy of repentance. As the Lord Himself said to Jerusalem: How often have I desired to gather your children together as a hen gathers her chicks under her wings, and you were not willing (Matthew 23:37).

But he appeared not so much for the eyes of human beings as for their salvation, for even though he was first seen by fleshly eyes when he was born of the virgin, still he did not appear because the eye of faith did not as yet recognize his power. Hence it is said to the Jews by the prophet: “Seeing you will see and will not see”; that is, the Savior whom they discerned with their fleshly eyes they did not see in a spiritual light.
