Mingled with these is a series of passages which foretell the destruction of the foe and the miraculous escape of Judah from imminent ruin, or, taking higher flight, picture the golden age to come. To the former class belong, for example, xxx. 27-33; xxxi. 4-9; to the latter, xxix. 18-24; xxx. 18-26; xxxii. 1-8, 16-20; while c. 33 partakes of both characters. That Isaiah predicted the deliverance of Jerusalem in the last extremity is reported also in Kings, and need not be questioned (see also Isa. x. 5-14; xiv. 24-27). Most of the prophecies of the golden age are, however, alien to their context, and the unmediated transition from the unsparing predictions of judgment to these messianic idylls makes them suspicious. It is not to be believed that the prophet thus took the sting out of his most pungent oracles, but the position of the passages in question can have no other intention. If, then, these are utterances of Isaiah at all, they cannot have been spoken in their present connection. Some of them, at least, are much more likely by other hands. This is true most evidently of c. 33, which was probably once the end of this little book of prophecies from the time of Sennacherib (Isa. 28-33).

Isaiah 34 is a prophecy against all the nations, which at once concentrates itself upon Edom, and is remarkable for its rancour, in which, as in other respects, it resembles cc. 13 f. The supernatural features of the judgment remind us also of Isa. 27: it is too little that the people are annihilated, its very land is turned into an uninhabitable waste, and, as by some prodigious volcanic convulsion, its dust becomes brimstone and its soil burning pitch. This is the Lord's vengeance for the wrong of Zion. The cause of this unusual passion is known from other prophets (see Obad. vss. 10-12; Ezek. xxv. 12-14; c. 35): in the life and death struggle against Nebuchadnezzar, the Edomites, Judah's next neighbours and near kin, had been on the side of the Babylonians, and were the chief gainers by the ruin of Judah, occupying permanently the whole south of the country to a line north of Hebron, making good in this way the part of their own old territory which had been taken by the Nabatæans. The injury was lasting and the hatred durable, but the flaming passion of Isa. 34 would incline us to think that it was written while the grief was still fresh. The pendant to this, Isa. 35, a prophecy of the return of the dispersion and restoration of Zion, is quite in the manner of Isa. 40 ff., and not improbably by the same author.

Of Isa. 36-39 (2 Kings 18-20) account has already been given (see above, pp. 112 f.).

There remains the anonymous prophetic book, Isa. 40-66, which not only has no title, but in which—in striking contrast to the frequency with which Isaiah's name occurs in the earlier chapters of the book—no prophet's name appears.

It begins with the announcement that the Jews have now been sufficiently punished for their sins; their guilt has been expiated by suffering. The hour of national restoration is at hand. God has already called the deliverer, who will bring low the pride of Babylon and set free captive Israel; by his edict Jerusalem shall be rebuilt and the temple restored. The Jews, not only from Babylonia but from the wide and distant lands of their dispersion, shall flock back to their own country, the cities of Judah shall be repeopled, and Zion shall be too strait for its inhabitants. The deliverer is Cyrus (Isa. xliv. 28; xlv. 1), who is called God's friend, his anointed one (messiah); the victories he has already gained have been won in the might of Jehovah, who, all unknown to him, girds him for the battle, and will go before him to new conquests.

The prophet's prediction was met with incredulity; the power of Babylon seemed invincible, the resurrection of the dead nation impossible. Impossible, maybe, to men, but not to the Almighty God, the creator of heaven and earth, the sovereign ruler of the nations! As surely as the words of former prophets have come true, so signally shall these foretellings be fulfilled. For history is the unfolding of God's plan from the beginning, which he reveals by chapters to his servants the prophets.

That this prophecy was delivered by Isaiah of Jerusalem, a century before the fall of Judah and a century and a half before the time of Cyrus, would never have entered anybody's head had these chapters not been appended to a roll which bore at its beginning the name of Isaiah and contained many oracles of the eighth-century prophet. But this physical fact, which may be due to no intention more profound than a desire to economize writing material, cannot count against the conclusive internal evidence; background and foreground in Isa. 40 ff. are not merely totally different from those of the prophecies of Isaiah and his contemporaries, they are alike inconceivable in his age. Nor is the fact that the Jews in New Testament times, including the New Testament writers, quoted these chapters as Isaiah and believed him the author of them, prove anything except that such was the opinion of the Jews in that age.

The historical situation in Isa. 40 ff. would of itself be conclusive against Isaiah's authorship; but it is not the only proof of the contrary. The author of these chapters has not inappropriately been called the theologian among the prophets. His idea of God is conspicuously more advanced than that of the prophets of the eighth century; it lies in the same line with the monotheism of Deuteronomy and Jeremiah, but lies beyond them. And it is characteristic that, in contrast to the older prophets, this one reasons about it. He argues the omnipotence of God in history from his omnipotence in creation, and makes large use of the evidence from the fulfilment of prophecy to prove that Jehovah is the only God; he can predict because he foreordains and brings to pass. With him begins the polemic, not against the worship of heathen gods, but against their existence. What the heathen bow down to are naught but helpless, senseless idols, the work of their own hands. He is fond of inviting his readers to an image-maker's shop to see how a god is made (see, e.g., Isa. xliv. 9-20). Such are the impotent gods that the Babylonians expect to save them out of the hands of the creator of the world!

The style of Isa. 40 ff. is not less decisive. Translation necessarily in large measure effaces the differences, but even in translation a comparison of two passages on similar themes such as Isa. x. 5-19 and Isa. 47 may perhaps give some impression of them. The style of Isaiah and his contemporaries—Amos, Hosea, Micah—is concise and pregnant, the sentences are short and have often an oracular ring. The author of Isa. 40 ff. writes with a freer pen in flowing periods; he develops his thought and his figures more at large; if he is obscure, it is seldom from compression. Here again, Deuteronomy and Jeremiah, the whole literature of the seventh century, is an intermediate stage. The later author is a poet, as Isaiah is, but with other themes and in other forms; compare, e.g., Isa. 5 with Isa. xlii. 1-9. In short, each has a highly characteristic style, and the two are totally different.

The historical situation, as it has been defined above, appears most distinctly in Isa. 40-55. In the following chapters two passages were long ago seen not to correspond to that situation, viz. lvi. 9-lvii. 13 and c. 65 (especially vss. 1-16), in which the vehement attack on idolatrous and abominable rites practised by Jews under the prophet's eyes was thought to indicate a pre-exilic origin. It was a serious error, however, to conceive that the so-called exile cured all the Jews once and for all of every inclination to heathenism; the history of the Seleucid period sufficiently proves the contrary. There is nothing in the chapters inconsistent with the view, now generally entertained, that these flaming denunciations were delivered in Palestine in the Persian or the Greek period; and there is no warrant for assuming that they were specifically addressed to the half-heathen population of the old territory of Israel, still less to the so-called Samaritan sect, that is, the worshippers at the rival temple on Gerizim.
