With chapter xlii. we reach a distinct stage in our prophecy. The preceding chapters have been occupied with the declaration of the great, basal truth, that Jehovah is the One Sovereign God. This has been declared to two classes of hearers in succession--to God's own people, Israel, in ch. xl., and to the heathen in ch. xli. Having established His sovereignty, God now publishes His will, again addressing these two classes according to the purpose which He has for each. Has He vindicated Himself to Israel, the Almighty and Righteous God, Who will give His people freedom and strength: He will now define to them the mission for which that strength and freedom are required. Has He proved to the Gentiles that He is the one true God: He will declare to them now what truth He has for them to learn. In short, to use modern terms, the apologetic of chs. xl.-xli. is succeeded by the missionary programme of ch. xlii. And although, from the necessities of the case, we are frequently brought back, in the course of the prophecy, to its fundamental claims for the Godhead of Jehovah, we are nevertheless sensible that with ver. 1 of ch. xlii. we make a distinct advance. It is one of those logical steps which, along with a certain chronological progress that we have already felt, assures us that Isaiah, whether originally by one or more authors, is in its present form a unity, with a distinct order and principle of development. The Purpose of God is identified with a Minister or Servant, whom He commissions to carry it out in the world. This Servant is brought before us with all the urgency with which Jehovah has presented Himself, and next to Jehovah he turns out to be the most important figure of the prophecy. Does the prophet insist that God is the only source and sufficiency of His people's salvation: it is with equal emphasis that He introduces the Servant as God's indispensable agent in the work. Cyrus is also acknowledged as an elect instrument. But neither in closeness to God, nor in effect upon the world, is Cyrus to be compared for an instant to the Servant. Cyrus is subservient and incidental: with the overthrow of Babylon, for which he was raised up, he will disappear from the stage of our prophecy. But God's purpose, which uses the gates opened by Cyrus, only to pass through them with the redeemed people to the regeneration of the whole world, is to be carried to this Divine consummation by the Servant: its universal and glorious progress is identified with his career. Cyrus flashes through these pages a well-polished sword: it is only his swift and brilliant usefulness that is allowed to catch our eye. But the Servant is a Character, to delineate whose immortal beauty and example the prophet devotes as much space as he does to Jehovah Himself. As he turns again and again to speak of God's omnipotence and faithfulness and agonising love for His own, so with equal frequency and fondness does he linger on every feature of
