This twofold division of the prophet's problem will not, it is true, strike his prophecy into separate and distinct groups of chapters. He who attempts such a division simply does not understand "Second Isaiah." But it will make clear to us the different currents of the sacred argument, which flow sometimes through and through one another, and sometimes singly and in succession; and it will give us a plan for grouping the twenty-seven chapters very nearly, if not quite, in the order in which they lie.
On these principles, the following exposition is divided into Four Books. The First is called THE EXILE: it contains an argument for placing the date of the prophecy about 550 B.C., and brings the history of Israel down to that date from the time of Isaiah; it states the political and spiritual sides of the double problem to which the prophecy is God's answer; it describes what Israel took with them into exile, and what they learned and suffered there, till, after half a century, the herald voices of our prophecy broke upon their waiting ears. The Second Book, THE LORD'S DELIVERANCE, discusses the political redemption from Babylon, with the questions attached to it about God's nature and character, about Cyrus and Babylon, or all of chs. xl.-xlviii., except the passages about the Servant, which are easily detached from the rest, and refer rather to the spiritual side of Israel's great problem. The Third Book, THE SERVANT OF THE LORD, expounds all the passages on that subject, both in chs. xl.-xlviii. and in chs. xlix.-liii., with the development of the subject in the New Testament, and its application to our life to-day. The Servant and his work are the solution of all the spiritual difficulties in the way of the people's Return and Restoration. To these latter and their practical details the rest of the prophecy is devoted; that is, all chs. xlix.-lxvi., except the passages on the Servant, and these chapters are treated in the Fourth Book of this volume, THE RESTORATION.
As much as possible of the merely critical discussion has been put in Chapter I., or in the opening paragraphs of the other chapters, or in foot-notes. A new translation from the original (except where a few verses have been taken from the Revised English Version) has been provided for nearly the whole prophecy. Where the rhythm of the original is at all discernible, the translation has been made in it. But it must be kept in mind that this reproduction of the original rhythm is only approximate, and that in it no attempt has been made to elegance; its chief aim being to make clear the order and the emphases of the original. The translation is almost quite literal.
