8:18 God of Hosts, who dwells on Mount Tzion
After describing the upcoming Assyrian invasion, the prophet takes steps to ensure that a small remnant of believers in Hashem’s salvation will remain. He goes so far as to name his children with names of hope and promise, as signs that the redemption will come. Yeshayahu points to the fact that God’s presence continues to reside on Mount Tzion. Regarding the Beit Hamikdash and Yerushalayim, the Rambam states, “even though it is destroyed, it still possesses its holiness.” This means that 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 (Deuteronomy 30:3-5).
