The name Shear-jashub means “A Mere Remnant (Those Remaining Over) Will Return.” This name was prophetic in that, just as certainly as a son born to Isaiah was given that name, so the kingdom of Judah would in time be overthrown and only a mere remnant would return after a period of exile. (Isa 7:3; 10:20-23)

The thing that undoubtedly gave Isaiah the greatest joy was the privilege accorded him by Jehovah to speak and to write many prophecies of restoration of his beloved Jerusalem. Although Jehovah would allow the people to go into exile to Babylon because of rebellion and revolt against him, God would in time judge Babylon because she acted out of malice and intended to hold God’s people in captivity forever. A number of Isaiah’s prophecies are devoted to God’s judgment on Babylon and the desolate ruin she would become, never to be rebuilt.​—Isa 45:1, 2; chaps 13, 14, 46-48.

The restoration prophecies that are found throughout the book of Isaiah glorify Jehovah’s undeserved kindness and mercy toward his people and toward all mankind. They foretell the time when Jerusalem would be elevated to a new position with Jehovah, a glory that would be seen by all nations, and when she would be a blessing to all nations. Jerusalem was indeed restored and rebuilt and was blessed by the presence of the Messiah, who “shed light upon life and incorruption through the good news.” (2Ti 1:10) Jerusalem’s restoration also had a greater and grander fulfillment to come.​—Ro 15:4; 1Co 10:11; Ga 4:25, 26.
