The moment of ultimate redemption brings with it an outburst of joy and an unprecedented level of revelation. After a long and painful wait, spiritual promises finally transform into a tangible reality, and quiet anticipation gives way to a unified, joyful song of the masses.
Those who have spent their lives looking toward the horizon play a central role in this event. Commentators offer different perspectives on who exactly these lookouts are. The most straightforward understanding is that they are physical guards stationed on city walls and tall towers, tasked with watching for anyone approaching the city to announce their arrival [רש״י, מצודת דוד, אבן עזרא]. Another perspective suggests that these observers are actually the prophets of Israel. Because they look into the future, they are considered spiritual watchmen; having prophesied messages of comfort in the past, they now live to see those promises fulfilled [רד״ק, ביאור שטיינזלץ]. Others identify them as the leaders of the nation [רד ק בשם התרגום], or even as stargazers who recognize shifts in the heavens signaling the arrival of the Messiah [אהבת יהונתן].
Regardless of their specific identity, when these lookouts finally notice the approaching salvation, they do not remain silent. Instead, they raise their voices in a shared song of joy. Under normal circumstances, guards are scattered across different posts and do not see or report events at the exact same moment. However, during the redemption, the revelation will be so clear that everyone will see, understand, and rejoice in the exact same fraction of a second [אדרת אליהו]. This profound unity also links the messenger standing on the mountain with the watchers down in the city, all cheering together at the sight of salvation [מלבי״ם].
The clarity of this event is absolute, representing a certain, open vision that leaves no room for doubt, much like seeing a close friend face-to-face [מצודת דוד, שד״ל]. The primary approach among commentators is that this represents a fundamental shift from abstract faith to visible reality. During the exile, future blessings could only be seen in the mind or through an inner prophetic vision. In the time to come, this spiritual and mental understanding will take on a physical form, allowing people to witness the redemption with their actual, physical eyes [מלבי״ם, אדרת אליהו, ביאור שטיינזלץ].
The ultimate focus of this clear vision is God's return to Zion. The watchers will physically witness God bringing His Divine Presence back to Jerusalem, just as it was in ancient days, fully restoring the kingship, the priesthood, and the Temple [מצודת דוד, מלבי״ם]. This monumental return will also bring back the spirit of prophecy that had vanished during the exile. It will return with an incredible force, matching the sheer power of the divine revelation experienced at Mount Sinai [רד״ק, צאינה וראינה].
