After long years of exile and steady anticipation, a moment will arrive when divine salvation becomes visible to all. Deep faith will finally transform into a clear, undeniable reality. At the time of this ultimate revelation, the Israelites will break into a song of profound gratitude [רש״י, רד״ק, אבן עזרא]. This declaration serves as a definitive response to the nations of the world who mocked the Israelites during their exile, taunting them and questioning the whereabouts of their God. Pointing with pride, the nation will declare that this is the God they had constantly hoped for, proving that their enduring patience was never in vain [מלבי״ם].
To express the absolute completeness of this process, the song calls out to God using two distinct names. The first name highlights the deeply personal and special connection between God and His people [מלבי״ם]. It also reflects the attribute of strict justice and the shared sorrow of the Divine Presence throughout the long exile [חומת אנך]. The second name shifts the focus to the attribute of mercy, representing the supreme power of the Creator and the supernatural magnitude of the redemption [מלבי״ם, חומת אנך]. The call for salvation captures the constant, unwavering anticipation the nation held for God's help [רש״י]. Furthermore, this is not a temporary rescue or a standard shift in the natural order, but rather an eternal and continuous salvation [אבן עזרא, מלבי״ם].
The nation's deep yearning was never solely about their own physical rescue. Primarily, they hoped for the honor of God's name and the clear revelation of His kingdom across the world, which is why their ultimate joy is focused specifically on His salvation [חומת אנך]. While the primary approach among commentators views this song as a description of the ultimate, future redemption, a different perspective limits its scope. According to this view, the praise refers exclusively to the historical return from the Babylonian exile and does not contain any hints about a future perfection of the world or the end of mortality [שד״ל].
The celebration concludes by describing two distinct stages of happiness. The first is an initial, sudden burst of intense emotion upon hearing the good news of salvation, much like the thrill of discovering a precious treasure. The second stage represents a deeper, more settled joy. It is the constant, peaceful, and eternal state of the heart that will remain with the nation forever, illuminated by the everlasting salvation they have finally received [מלבי״ם].
