Jesaja 42:8

Jehovah pledges His name and honour that this work of the Servant of Jehovah will be carried into effect. "I am Jehovah; that is my name, and my glory I give not to another, nor my renown to idols." That is His name, which affirms how truly He stands alone in His nature, and recals to mind the manifestations of His life, His power, and His grace from the very earliest times (cf., Exo 3:15). He to whom this name belongs cannot permit the honour due to Him to be permanently transferred to sham gods. He has therefore made preparations for putting an end to idolatry. Cyrus does this provisionally by the tempestuous force of arms; and the Servant of Jehovah completes it by the spiritual force of His simple word, and of His gentle, unselfish love.

The prophet seems here to launch out yet further into the prophecy of the Messiah and his kingdom under the type of Cyrus; and, having the great work of man's salvation by him yet more in view, he almost forgets the occasion that led him into it and drops the return out of Babylon; for indeed the prospect of this would be a greater comfort and support to the believing pious Jews, in their captivity, than the hope of that. And (as Mr. Gataker well observes) in this and similar prophecies of Christ, that are couched in types, as of David and Solomon, some passages agree to the type and not to the truth, other to the truth and not to the type, and many to the type in one sense and the truth in another. Here is, I. A prophecy of the Messiah's coming with meekness, and yet with power, to do the Redeemer's work (Isa 42:1-4). II. His commission opened, which he received from the Father (Isa 42:5-9). III. The joy and rejoicing with which the glad tidings of this should be received (Isa 42:10-12). IV. The wonderful success of the gospel, for the overthrow of the devil's kingdom (Isa 42:13-17). V. The rejection and ruin of the Jews for their unbelief (Isa 42:18-25).

42:8-9 I am the Lord: As Creator of the world, and as the only one who can bring about the things he predicts, the Lord alone is glorious and worthy of praise.
