A time of ultimate salvation and absolute security awaits Judah and Jerusalem in the future. This coming era of peace will be so profound that it will be reflected in a new identity for the city itself [ביאור שטיינזלץ]. There are different perspectives on who will actually declare this new name. It may be God Himself who bestows this title upon Jerusalem, or it might be the city's own residents who choose to call it by this name [רד״ק]. Beneath the surface, the very act of naming represents a deep spiritual bond, signifying a great and public unification between God and the Divine Presence [חומת אנך].
Jerusalem's new name, "God is our righteousness," serves as a constant reminder that God is the ultimate source of salvation [ביאור שטיינזלץ]. It stands as a testament that God will justify the Israelites as long as the city endures [מצודת דוד]. Additionally, the name symbolizes the good deeds and merits that the people will perform before God within Jerusalem's walls [רד״ק].
This specific title mirrors the name given to the Messianic king in an earlier prophecy, with both names pointing toward the exact same truth and purpose [רד״ק]. Ultimately, on a deeper spiritual level, this new identity reflects a state of complete and perfect harmony within the higher realms [חומת אנך].
