Thus the earlier part, at least, of Isa. xl.-lxvi.--that is, chs. xl.-xlviii.--compels us to date it between 555, Cyrus' advent, and 538, Babylon's fall. But some think that we may still further narrow the limits. In ch. xli. 25, Cyrus, whose own kingdom lay east of Babylonia, is described as invading Babylonia from the north. This, it has been thought, must refer to his union with the Medes in 549, and his threatened descent upon Mesopotamia from their quarter of the prophet's horizon.[4] If it be so, the possible years of our prophecy are reduced to eleven, 549-538. But even if we take the wider and more certain limit, 555 to 538, we may well say that there are very few chapters in the whole of the Old Testament whose date can be fixed so precisely as the date of chs. xl.-xlviii.
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]
