“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.”

“Thou hast heard, see all this: and will ye not declare it?.... You have heard of all these things, how they were foretold before they were; how they came to pass exactly as they were predicted; now look over these prophecies, and compare them with the events; see the exact completion of them; and when you have so done, can you be so stouthearted and impudent as to deny them, or not own and confess them? I have showed thee new things from this time, even hidden things, and thou didst not know them; meaning the destruction of the Babylonish empire, and the deliverance of the Jews by Cyrus, prophesied just now in the preceding chapters; things not yet come to pass, newly revealed, which were hidden in the breast of God, and unknown to them until prophesied of; and which were typical of redemption by the incarnate Son of God, whose incarnation, and salvation by him, were new, unheard of, and wonderful things; and of the new state of things under the Gospel dispensation, when all things shall become new; the doctrines and ordinances of which are new; the whole Gospel is a hidden mystery, and unknown to men till revealed and made known by the Spirit of God.”

“Thou, &c.--So "ye are my witnesses" (Isa 43:10). Thou canst testify the prediction was uttered long before the fulfilment: "see all this," namely, that the event answers to the prophecy. declare--make the fact known as a proof that Jehovah alone is God (Isa 44:8). new things--namely, the deliverance from Babylon by Cyrus, new in contradistinction from former predictions that had been fulfilled (Isa 42:9; Isa 43:19). Antitypically, the prophecy has in view the "new things" of the gospel treasury (Sol 7:13; Mat 13:52; Co2 5:17; Rev 21:5). From this point forward, the prophecies as to Messiah's first and second advents and the restoration of Israel, have a new circumstantial distinctness, such as did not characterize the previous ones, even of Isaiah. Babylon, in this view, answers to the mystical Babylon of Revelation. hidden--which could not have been guessed by political sagacity (Dan 2:22, Dan 2:29; Co1 2:9-10).”

“But in order to determine exactly what "the former things" were, which Jehovah had foretold in order that Israel might not ascribe them to this idol or the other, we must add Isa 48:6-8 : "Thou hast heard it, look then at it all; and ye, must ye not confess it? I give thee new things to hear from this time forth, and hidden things, and what thou didst not know. It is created now, and not long ago; and thou hast not heard it before, that thou mightest not say, Behold, I knew it. Thou hast neither heard it, nor known it, nor did thine ear open itself to it long ago: for I knew thou art altogether faithless, and thou art called rebellious from the womb." The meaning of the question in Isa 48:6 is very obvious: they must acknowledge and attest, even thou against their will (Isa 43:10; Isa 44:8), that Jehovah has foretold all that is now confirmed by the evident fulfilment. Consequently the "former things" are the events experienced by the people from the very earliest times (Isa 46:9) down to the present times of Cyrus, and more especially the first half or epoch of this period itself, which expired at the time that formed the prophet's standpoint. And as the object of the prediction was to guard Israel against ascribing to its idols that which had taken place (which can only be understood of events that had occurred in favour of Israel), the "former things" must include the preparation for the redemption of Israel from the Babylonian captivity through the revolution brought to pass by Cyrus. Hence the "new things" will embrace the redemption of Israel with its attendant circumstances, and that not merely on its outward side, but on its spiritual side as well; also the glorification of the redeemed people in the midst of a world of nations converted to the God of Israel, and the creation of a new heaven and a new earth; in short, the New Testament aeon (compare עם לברית, lxx εἰς διαθήκην γένους, Isa 42:6), with the facts which contribute to its ultimate completion (f. Isa 42:9). The announcement and realization of these absolutely new and hitherto secret things (cf., Rom 16:25) take place from this time forward; Israel has not heard of them "before today" (compare מיּום, "from this day forward," Isa 43:13), that it may not lay claim to the knowledge conveyed to it by prophecy, as something drawn from itself. This thought is carried to a climax in Isa 48:8 in three correlated sentences commencing with "yea" (gam). פּתח signifies patescere here, as in Isa 60:11 (Ewald, 120, a). Jehovah had said nothing to them of this before, because it was to be feared that, with their faithlessness and tendency to idolatry, which had run through their entire history, they would only abuse it. This is strange! On the one hand, the rise of Cyrus is spoken of here as predicted from of old, because it belonged to the "former things," and as knowable through prophecy - a statement which favours the opinion that these addresses were written before the captivity; and, on the other hand, a distinction is drawn between these "former things" and certain "new things" that were intentionally not predicted before the expiration of these "former things," which certainly seems to preclude the possibility of their having been composed before the captivity; since, as Ruetschi observes, if "the older Isaiah had predicted this, he would have acted in direct opposition to Jehovah's design." But in actual fact, the dilemma in which the opponents of the authenticity of these prophecies find themselves, is comparatively worse than this. For the principal objection - namely, that a prophet before the captivity could not possibly have known or predicted anything concerning Cyrus - cannot be satisfactorily removed by attributing these prophecies to a prophet of the time of the captivity, since they expressly and repeatedly affirm that the rise of Cyrus was an event foreknown and predicted by the God of prophecy. Now, if it is Isaiah who thus takes his stand directly in the midst of the captivity, we can understand both of these: viz., the retrospective glance at previous prophecies, which issued in the rise of Cyrus that prepared the way for the redemption from Babylon, since, so far as the prophet was concerned, such prophecies as Isaiah 13-14:23; Isa 21:1-10, and also Isa 11:10-12 (Mic 4:10), are fused into one with his present predictions; and also the prospective glance at prophecies which are now first to be uttered, and events which are now fore the first time about to be accomplished; inasmuch as the revelations contained in these prophecies concerning Israel's pathway through suffering to glory, more especially so far as they grew out of the idea of the "servant of Jehovah," might really be set down as absolutely new to the prophet himself, and never heard of before. Meanwhile our exposition is not affected by the critical question; for even we most firmly maintain, that the prophet who is speaking here has his standpoint in the midst of the captivity, on the boundary line of the condition of suffering and punishment and its approaching termination.”
