Isaiah 28:5,6

Jehovah Himself the true glory of His people; a Messianic pendant to the foregoing picture of Samaria's fall. The phrase in that daypoints as usual to the indefinite future of the Messianic age, not to the day of the judgment on North Israel. Whether the "remnant of His people" denotes the survivors of the Northern tribes, or those of Judah, or of the whole nation, it means a converted remnant; and there is no reason to suppose that Isaiah at any time expected the conversion of Judah to follow immediately the destruction of Ephraim. He is here looking beyond the whole series of national judgments, and the insertion of the promise is evidently suggested by the contrast between the false glory that has vanished and the true glory which shall endure.
