Thou hast neither heard, nor known, neither was thy ear opened of old. For I know that transgressing thou wilt transgress, and I have called thee a transgressor from the womb.

“Neither did you hearken Jonathan renders: Neither did you hearken to the words of the prophets, neither did you accept the teaching of the Torah, nor did you bend your ear to the words of the blessings and the curses of My covenant that I established with you at Horeb. for I knew that you would deal treacherously When I came down to save you from the hands of the Egyptians, it was revealed to Me that you would eventually deal treacherously. Nevertheless, I kept the oath of the Patriarchs. This is what is stated (Ex. 3:7): “I saw the affliction of My people.” [The Hebrew expression for “I saw,” is רָאֹה רָאִיתִי, a double verb form, which denotes] two seeings. I see that they will eventually deal treacherously, but, nevertheless, I saw the affliction of My people. Rabbi Tanhuma expounded it in this manner. and...transgressor from the womb Since you were in Egypt, as it is related in Ezekiel (20:5): “And I made Myself known in the land of Egypt, etc. (v. 7) and I said to them, [Cast away, each man the abominations of his eyes, and do not contaminate yourselves with the idols of Egypt].””

“Yea, thou knowest not, etc., I knew, etc. That is, I know it for certain, that thou hast not heard of it, or I knew it, that thou wouldst not listen, that thou wouldst be treacherous against me, and not believe in my words. From the womb. I knew thee since thou camest to existence. In the opposite sense this expression is used in Jer. 1:5: Before I formed thee in the belly, I knew thee. And thou wast called a transgressor from the womb. This refers to the decrees of the Almighty. I shall fully explain this subject in my commentary on the book of Jeremiah. פתחה Hath opened itself; it is an elliptical expression.”

“Hear this, O house of Jacob, etc. Here he promises the liberation of the people. And it is divided into two parts. In the first he promises the liberation; in the second he carries out the order of the liberation, below, chapter 49: Hear, O islands, etc. The first is divided into two. In the first he arouses attention, calling to mind three things in which they gloried: namely, the dignity of their lineage, because they were from holy fathers: "of the waters," that is, of the seed. Against which, Matthew 3: "Do not think to say," etc.; the privilege of the knowledge of God: "who swear" — calling upon his name — "and remember" — as to the knowledge of him — "in truth," of heart, "nor in justice," of work. Above, chapter 29: "This people, with their lips, me," etc.; the worship of sacred religion: "from the city" — namely Jerusalem, in which was the worship of sacrifices — "they are called" — men of Jerusalem — 2 Maccabees 5: "not for the sake of the place, the nation," etc. Secondly he promises the liberation: "the former things, from that time," and concerning this he does three things. First he shows the majesty of God who promises; secondly, the prosperity of Cyrus who carries it out: "Assemble yourselves, all of you," etc.; thirdly he promises the liberation: "Come near to me," etc. Concerning the first, two things. First he shows the majesty of God from the foretelling of future things; secondly from the creation of things: "Hearken to me, Jacob," etc. Concerning the first, three things. First he assigns the reason for the foretelling of certain future things, setting down the foretelling itself: "the former things" — namely those which have already passed — "from that time," when they were still future, "suddenly," as regards others to whom they were not foretold. Ecclesiasticus 42: "declaring the things that have passed," etc.; setting down also the reason for this, which is taken from their condition — which he first states, "for I knew," from eternity. "That thou art hard" — hard to come to one's senses from evils; "thy neck" — that is, the stiffness of one's own judgment; "a sinew of iron," which cannot be bent; "thy forehead" — on account of shamelessness. Acts 5: "stiff-necked," etc.; Deuteronomy 31: "I know the contention," etc.; Jeremiah 3: "the forehead of a harlot," etc.; and then from this he draws out the reason, "I foretold," etc., as if to say: because thou wert prone to idolatry, I foretold it to thee, lest thou shouldst ascribe my benefits to idols. Hosea 2: "I will go after lovers," etc.; setting down also the manifestation of the things foretold: "which thou hast heard" — foretold to thee by me — "behold," fulfilled. Psalm 47: "As we have heard, so have we seen," etc. Secondly he assigns the reason for the concealment of certain future things, setting down first the concealment itself. As has been said, certain future things I foretold to thee; but certain future things have been kept in my foreknowledge, which thou dost not know, because I have not revealed them to thee. "Now" — that is, in time — "they are created," that is, brought forth in effect, and not from that time when I foreknew them; and "before the day" of their fulfillment, "thou hast not heard" of them, neither from me nor from the idols. 4 Kings 4: "the Lord hath hid it from me," etc. He also assigns the reason for this: "lest perhaps," as if to say: I did not reveal it for this reason, that thou mightest perceive thy own defect, and that of thy gods, in that thou canst not foreknow future things except those which I reveal to thee. "I have known" — by my own effort — "nor hast thou heard" — from the idols — the things opened by me. Psalm 63: "Man shall come to a deep heart," etc. He also sets down their condition, from which the aforesaid reason is drawn: "for I know." "From the womb" — that is, from the time when I carried thee through the desert as in a womb. Exodus 32: "I see that this people," etc.; above, chapter 24: "by the transgression of the transgressors," etc. Thirdly he excludes a certain objection: "for my name's sake." For someone could ask: since they are so hard, why then dost thou promise them good things, and hast done so? And to this objection he first sets down the response, recalling three benefits shown to them: "for my name's sake" — not on account of thy merit — "I will put far off," or have put far off, freeing them from punishments. Ezekiel 36: "Not for your sakes will I do this," etc., and "for my praise" — that is, I bound thee to my ceremonies and my praises, lest, offering sacrifices to idols, thou shouldst perish. Psalm 31: "with bit and bridle," etc. "I have refined," wishing to purge thee through tribulations, "but not as silver," which is purged. But thou hast not been corrected. Jeremiah 6: "in vain hath he melted," etc. "I have chosen," purging thee, namely, through poverty, punishing thee by the spoiling of goods. Gregory: "those whom the infirmity of their conduct wounds, the medicine of poverty heals." And this by correcting as a father. Secondly he sets down the exposition of the response: "for my own sake" — that I not be blasphemed, as though powerless to save the people whom I have chosen for myself; and "my glory" — namely, that the idols be judged stronger than I. Above, chapter 42: "my glory," etc. Hearken to me. Here he shows the divine majesty from the creation of things. "I will call," imposing upon each thing its proper work: "they shall stand," ready to obey. Above, chapter 40: "who hath weighed with three fingers," etc. Assemble yourselves, etc. Here he foretells the prosperity of Cyrus himself; and first he shows the concealment of this deed from others: "who among them?" — namely, among the idols — as if to say: none. Above, chapter 41: "who hath declared from the beginning," etc. Secondly he himself foretells his prosperity: "the Lord hath loved him" — namely Cyrus — advancing him into the kingdom; "in Babylon," capturing it; "his arm" — that is, by his own power slaying them. 1 Kings 27: "and indeed doing," etc. Thirdly he assigns the reason for his prosperity from divine aid: "I, I," etc.; "directed," not absolutely, but to this end, that he might destroy Babylon; otherwise it could not be expounded of Cyrus, but only of Christ, as Jerome says, because he was an idolater. Psalm 106: "he led them into the way," etc. Come near to me, etc. Here he promises liberation; and concerning this he does three things. First he arouses attention, setting down the divine authority: "in secret" — yet all the people saw the voices: Exodus 20. "From the beginning" — of the law given. "From the time," past, before they came to pass — the things which I foretell — "there I was," present to those future things, remaining, through the same "now" of eternity, throughout the whole succession of time. Or in the person of the Son, "there I was" — namely, in the Father according to his divinity — Proverbs 8: "when he weighed the foundations," etc.; setting down the truth of the prophet — who was sent by God — "and now, me": Isaiah, or me, Christ made man; "God," the Father; whence the three Persons are designated. Below, chapter 61: "the spirit of the Lord is upon me," etc. Secondly, there, "thus saith the Lord," he sets down the reason for the captivity, showing on God's part the help that was prepared. "Teaching" — against ignorance — and "governing in the way," of works, against weakness in acting. Psalm 31: "I will give thee understanding, and I will instruct," etc.; showing also the harm arising from the fault of the Jews. "O that thou hadst hearkened" — keeping them — "as an abundant river," "as the waves." The same, Psalm 80: "if my people had heard," etc. Thirdly, there, "go forth," he foretells the liberation; and concerning this he does three things. First he announces to them the departure from captivity, as certain of the liberation as if it were already present. "Go ye forth," etc.; Apocalypse 18: "go out from her," etc.; and he charges them to announce the benefit of God. "Declare ye," etc.; Jeremiah 50: "the voice of them that flee, and of them that have escaped," etc. Secondly he designates the benefit of consolation bestowed on those freed: "they thirsted not" — that is, the Lord will provide for them in all things just as when they went out from Egypt. Psalm 77: "he struck the rock, and they flowed," etc.; Numbers 21. Thirdly he takes away from the wicked the solace of peace: "there is no peace," below, chapter 57; 4 Kings 9: "what hast thou to do with peace," etc. (Collations, chapter 48) Poverty confers: the recognition of sins: "if they shall be bound," etc.; the preservation of virtues, Ecclesiasticus 10: "the poor man glorieth," etc.; quiet of heart, Tobit 5: "it was enough for us," etc.; the fulfillment of desire, Psalm: "the desire of the poor," etc.; participation in the divine sweetness, Psalm: "thou hast prepared in sweetness," etc.; exaltation, 1 Kings 2: "raising up from the dust," etc.; the heavenly inheritance, Matthew 5: "blessed are the poor," etc. The words of God are useful: for the illumination of the understanding, Proverbs 6: "the commandment is a lamp," etc.; for the delight of the affections, Psalm: "how sweet to the jaws," etc.; for the kindling of love, Jeremiah 20: "it came to be in the heart," etc.; Psalm: "the word of the Lord"; for the rightness of work, Psalm: "direct me in truth," etc.; for the attainment of glory, Proverbs 3: "keep the law"; for the instruction of others, 2 Timothy 3: "all doctrine divinely," etc.”

“Yea, thou heardest not; yea, thou knewest not yea, from that time that thine ear was not opened,.... This, as Kimchi rightly observes, is said by way of reproof; showing that they were so far from knowing these things before the prophecy of them was given out, that when it was, they did not hearken or listen to them; they did not understand them, nor receive and embrace them, but turned a deaf ear to them; their hearts being hardened, and they given up blindness of mind; which was the case of the Jews, even when the Messiah, the antitype of Cyrus, came, and there was a more clear revelation of Gospel truths, as was foretold, Isa 6:9. To this sense is the Targum, "yea, thou has not heard the words of the prophets; yea, thou hast not received the doctrine of the law; yea, thou hast not inclined thine ear to the words of the blessings and curses of the covenant I made with thee at Horeb:'' for I knew that thou wouldest deal very treacherously: with God, and with one another, as they did; and were, as Jeremiah calls them, an assembly of treacherous men; and especially so they were in Christ's time, and to him; one of his own disciples treacherously betrayed him into the hands of the Jews, and they delivered him into the hands of the Gentiles to be crucified and slain; all which he knew before hand, Joh 6:64. And so the Lord knows all the wickedness and unfaithfulness of men, and of his own people, who are by nature children of wrath, as, others; yet this hindered not the designs of his grace, and the discoveries of his love to them, after expressed: and wast called a transgressor from the womb; from the time of their civil birth, as a people and state, God was their Father that settled and established them; in this sense they were his children, whom he begot, brought up, and nourished; though they rebelled against him, and as soon almost as born, soon after they came out of Egypt, which were the days of their youth, of their infancy as a church and people; witness their murmurings and unbelief, their idolatry in making a golden calf, and worshipping it: and this is applicable to every particular person, and his natural birth, even to everyone of God's elect; who are all conceived in sin, and shapen in iniquity; go astray from God from the womb; and the imagination of whose heart is evil from their youth, and are continually transgressing the righteous law of God, and therefore justly deserve this name.”

“Opened; docile, (Theodoret) or acquainted with these things. Isaias first made known the captivity of Babylon, and its end; and he insists so much, that people may discern the truth of his predictions, and of religion. No atheist can, with a good conscience, hold out against his arguments, chap. xl., &c.”

“heardest not--repeated, as also "knewest not," from Isa 48:7. from that time--Mine anger towards thee. Omit "that." "Yea, from "the first thine ear did not open itself," namely, to obey them [ROSENMULLER]. "To open the ear" denotes obedient attention (Isa 50:5); or, "was not opened" to receive them; that is, they were not declared by Me to thee previously, since, if thou hadst been informed of them, such is thy perversity, thou couldst not have been kept in check [MAURER]. In the former view, the sense of the words following is, "For I knew that, if I had not foretold the destruction of Babylon so plainly that there could be no perverting of it, thou wouldst have perversely ascribed it to idols, or something else than to Me" (Isa 48:5). Thus they would have relapsed into idolatry, to cure them of which the Babylonian captivity was sent: so they had done (Exo 32:4). After the return, and ever since, they have utterly forsaken idols. wast called--as thine appropriate appellation (Isa 9:6). from the womb--from the beginning of Israel's national existence (Isa 44:2).”
