Let them give glory unto the Lord … in the islands; i.e. "let those who are in the islands," or the maritime tracts, "give glory to God"—a repetition of the last clause of Isaiah 42:10. The persistency with which the islands, or the maritime tracts of the west, are mentioned (Isaiah 41:1, Isaiah 41:5; Isaiah 42:10, Isaiah 42:12; Isaiah 49:1, etc.
) may perhaps be accounted for by the fact that Christianity was to obtain its earliest and its most enduring triumphs in these regions.
