Isaiah 42:15

The delivery takes place, and the whole world of nature undergoes a metamorphosis, which is subservient to the great work of the future. "I make waste mountains and hills, and all their herbage I dry up, and change streams into islands, and lakes I dry up." Here is another example of Isaiah's favourite palindromy, as Nitzsch calls this return to a word that has been used before, or linking on the close of a period of its commencement. Jehovah's panting in labour is His almighty fiery breath, which turns mountains and hills into heaps of ruins, scorches up the vegetation, condenses streams into islands, and dries up the lakes; that is to say, turns the strange land, in which Israel has been held captive, into a desert, and at the same time removes all the hindrances to His people's return, thus changing the present condition of the world into one of the very opposite kind, which displays His righteousness in wrath and 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).
