Isaiah 49:6

Glorious things had been spoken in the previous chapters concerning the deliverance of the Jews out of Babylon; but lest any should think, when it was accomplished, that it looked much greater and brighter in the prophecy than in the performance, and that the return of about 40,000 Jews in a poor condition out of Babylon to Jerusalem was not an event sufficiently answering to the height and grandeur of the expressions used in the prophecy, he here comes to show that the prophecy had a further intention, and was to have its full accomplishment in a redemption that should as far outdo these expressions as the other seemed to come short of them, even the redemption of the world by Jesus Christ, of whom not only Cyrus, who was God's servant in foretelling it, was a type. In this chapter we have, I. The designation of Christ, under the type of Isaiah, to his office as Mediator (Isa 49:1-3). II. The assurance given him of the success of his undertaking among the Gentiles (Isa 49:4-8). III. The redemption that should be wrought by him, and the progress of that redemption (Isa 49:9-12). IV. The encouragement given hence to the afflicted church (Isa 49:13-17). V. The addition of many to it, and the setting up of a church among the Gentiles (Isa 49:18-23). VI. A ratification of the prophecy of the Jews' release out of Babylon, which was to be the figure and type of all these blessings, (Isa 49:24-26). If this chapter be rightly understood, we shall see ourselves to be more concerned in the prophecies relating to the Jews' deliverance out of Babylon than we thought we were.

49:6 a light to the Gentiles: As the Messiah, the servant’s mission would have a worldwide reach (see 11:10, 12; 42:6). The apostle Paul explained his apostolic mission to the Gentiles on the basis of this prophecy (Acts 13:47; 26:23).
