After describing the impending Assyrian invasion, Isaiah takes steps to ensure that a small number of believes in Hashem‘s (God’s) salvation will remain. He goes so far as to give his children names of hope and promise, as signs that the redemption will come. Isaiah points to the fact that God’s presence continues to reside on Mount Tzion. Hashem will never abandon His land or His people. Instead, He remains with His children even while they are in exile, and guarantees that He will redeem them at the right time.
