Isaiah 42:10

"Sing unto Jehovah a new song, and his praise from the end of the earth; ye that go down to the sea, and all that is therein, the isles, and the inhabitants thereof. Let the wilderness and the cities thereof lift up their voice, the villages that Kedar doth inhabit; let the inhabitants of Sela sing, let them shout from the top of the mountains. Let them give glory unto Jehovah, and declare his praise in the islands. Jehovah will go forth as a mighty man; he will stir up his zeal like a man of war: he will cry, yea, he will shout aloud; he will do mightily against his enemies."

Concerning these verses, Archer noted that, "These represent the Gentiles as singing praises to God for their deliverance and conversion, and rejoicing with Israel over God's conquest over all his foes."[13] How marvelous all over the world has been the fulfillment of this prophecy of Christian singing. Creeds and doctrines are disputed and are even found to be contradictory; but the whole Christian world rejoices in the great songs of God's church. No Old Testament prophecy was ever more gloriously fulfilled than this one has been. As Henderson commented, "This paragraph describes the universal joy which the publication of the Gospel should occasion."[14]

Both Kedar and Sela were bitter enemies of Israel. Sela was one name of the Edomite city also called Petra, thus both of these being accounted Gentiles by the Jews. "Their mention here demonstrates the breadth of God's grace; but see the next paragraph."[15]
