If what has been unfolded in the preceding paragraphs is recognised as the statement of the chapters themselves, it will be felt that further evidence of an exilic date is scarcely needed. And those, who are acquainted with the controversy upon the evidence furnished by the style and language of the prophecies, will admit how far short in decisiveness it falls of the arguments offered above. But we may fairly ask whether there is anything opposed to the conclusion we have reached, either, _first_, in the local colour of the prophecies; or, _second_, in their language; or, _third_, in their thought--anything which shows that they are more likely to have been Isaiah's than of exilic origin.
1. It has often been urged against the exilic date of these prophecies, that they wear so very little local colour, and one of the greatest of critics, Ewald, has felt himself, therefore, permitted to place their home, not in Babylonia, but in Egypt, while he maintains the exilic date. But, as we shall see in surveying the condition of the exiles, it was natural for the best among them, their psalmists and prophets, to have no eyes for the colours of Babylon. They lived inwardly; they were much more the inhabitants of their own broken hearts than of that gorgeous foreign land; when their thoughts rose out of themselves it was to seek immediately the far-away Zion. How little local colour is there in the writings of Ezekiel! Isa. xl.-lxvi. has even more to show; for indeed the absence of local colour from our prophecy has been greatly exaggerated. We shall find as we follow the exposition, break after break of Babylonian light and shadow falling across our path,--the temples, the idol-manufactories, the processions of images, the diviners and astrologers, the gods and altars especially cultivated by the characteristic mercantile spirit of the place; the shipping of that mart of nations, the crowds of her merchants; the glitter of many waters, and even that intolerable glare, which so frequently curses the skies of Mesopotamia (xlix. 10). The prophet speaks of the hills of his native land with just the same longing, that Ezekiel and a probable psalmist of the Exile[5] betray,--the homesickness of a highland-born man whose prison is on a flat, monotonous plain. The beasts he mentions have for the most part been recognised as familiar in Babylonia; and while the same cannot be said of the trees and plants he names, it has been observed that the passages, into which he brings them, are passages where his thoughts are fixed on the restoration to Palestine.[6] Besides these, there are many delicate symptoms of the presence, before the prophet, of a people in a foreign land, engaged in commerce, but without political responsibilities, each of which, taken by itself, may be insufficient to convince, but the reiterated expression of which has even betrayed commentators, who lived too early for the theory of a second Isaiah, into the involuntary admission of an exilic authorship. It will perhaps startle some to hear John Calvin quoted on behalf of the exilic date of these prophecies. But let us read and consider this statement of his: "Some regard must be had to the time when this prophecy was uttered; for since the rank of the kingdom had been obliterated, and the name of the royal family had become mean and contemptible, during the captivity in Babylon, it might seem as if through the ruin of that family the truth of God had fallen into decay; and therefore he bids them contemplate by faith the throne of David, which had been cast down."[7]
2. What we have seen to be true of the local colour of our prophecy, holds good also of its style and language. There is nothing in either of these to commit us to an Isaian authorship, or to make an exilic date improbable; on the contrary, the language and style, while containing no stronger nor more frequent resemblances to the language and style of Isaiah than may be accounted for by the natural influence of so great a prophet upon his successors, are signalised by differences from his undisputed oracles, too constant, too subtle, and sometimes too sharp, to make it at all probable that the whole book came from the same man. On this point it is enough to refer our readers to the recent exhaustive and very able reviews of the evidence by Canon Cheyne in the second volume of his Commentary, and by Canon Driver in the last chapter of _Isaiah: His Life and Times_, and to quote the following words of so great an authority as Professor A. B. Davidson. After remarking on the difference in vocabulary of the two parts of the Book of Isaiah, he adds that it is not so much words in themselves as the peculiar uses and combinations of them, and especially "the peculiar articulation of sentences and the movement of the whole discourse, by which an impression is produced so unlike the impression produced by the earlier parts of the book."[8]
