A powerful cry of thanksgiving concludes a song of rescue, marking a profound moment of divine intervention and the deep happiness that follows. The primary approach among commentators is that this special time refers to a day of salvation and redemption. While some view it as a specific, immediate rescue, others understand it as the ultimate end of days, a future redemption predetermined by God [אלשיך].
This salvation is completely wondrous [אבן עזרא], an event that would be impossible without God stepping in directly [רד״ק]. Because God is the sole author of this rescue, it carries a permanent quality. Unlike the temporary achievements of human beings, a redemption forged by His hand is guaranteed to be eternal and last forever [מצודת דוד].
God brought about this miraculous event specifically so that people would respond with celebration [אבן עזרא]. The resulting joy unfolds in two distinct ways. Some view these reactions as simple synonyms for happiness [מצודת ציון], but others note a careful emotional progression. The initial response is a sudden, intense outburst triggered by the shock of the new reality exactly at the moment of rescue. This immediate thrill then settles into a constant, enduring state of gladness that continues long after the event [מלבי״ם]. Ultimately, this celebration carries a dual focus: it is a call to rejoice in the actual day of salvation itself, or, more deeply, to rejoice in God who performed the wonder [ביאור שטיינזלץ].
