ANNOUNCEMENT OF THE COMING DELIVERANCE OF ISRAEL FROM BABYLON, AND CALL ON THE NATIONS FOR A SONG OF PRAISE AND JUBILATION. Jehovah is still the speaker. He begins by promising a new revelation (Isaiah 42:9).
Then, before the revelation is made, he calls upon the nations—especially those in the vicinity of Palestine—to rejoice at what is about to happen (Isaiah 42:10-12). After this he proceeds to make the announcement promised in Isaiah 42:9—an announcement that he is about to deliver his people (Isaiah 42:16) and to execute vengeance on their enemies (Isaiah 42:13-15 and Isaiah 42:17).
