ישעיהו, פרק מ״ט, פסוק ו׳

A message of profound comfort and sweeping empowerment is delivered to a prophet who feels the sting of unfulfilled potential. Struggling with the frustration of an unresponsive generation, he receives a divine assurance that his current efforts are merely the beginning of a much grander, universal purpose [מלבי״ם].

God addresses the prophet's perceived limitations by reframing the scope of his calling. The primary approach among commentators is that God views the mere restoration of the Israelites as too small a gift and too simple a task for someone of the prophet's spiritual stature. Because he is destined for far more, he will ultimately receive a vastly greater role and reward [רש״י, מצודת דוד, אבן עזרא, שד״ל, שטיינזלץ]. Another perspective interprets God's message as a rhetorical question, asking if the prophet considers being God's servant a minor thing. Even if his contemporaries refuse to listen, the very act of carrying out God's mission is an immense, inherent privilege [רד״ק].

The prophet's original, national mission centers on raising up the tribes and restoring the people, though commentators differ on the exact nature of this restoration. One approach views it through a psychological lens, describing the Israelites as people whose hearts are besieged and closed off by negative desires, requiring the prophet to lead them to repentance [רש״י, מצודת דוד, שטיינזלץ]. Another view interprets the restoration physically, referring to the rebuilding of ruined and desolate places [אבן עזרא, רד״ק, שד״ל]. A third perspective likens the people to a tender branch or shoot [מנחת שי]. Expanding on this botanical metaphor, a distinction is made between the different factions of the nation. The exiled ten tribes were completely uprooted from their place, requiring them to be entirely raised up from their fall. In contrast, the remaining tribes of Judah and Benjamin are like a young shoot still attached to its soil; because they merely strayed from the path rather than falling completely, they simply need to be guided back [מלבי״ם].

Having established that the national mission is too small for the prophet, God expands his destiny to encompass all of humanity, appointing him as a guiding light and a source of salvation to the ends of the earth. The primary approach understands this as a global spiritual awakening in the End of Days. The prophet's words will illuminate the true faith for the entire world, and as the nations witness these prophecies coming to life, they will embrace goodness and experience God's salvation alongside Israel [מלבי״ם, רד״ק, מצודת דוד, שטיינזלץ]. Others narrow this light to specific historical events, suggesting the prophet will bring worldwide joy by announcing the impending downfall of the Babylonian army [רש״י] or by proclaiming God's salvation before it even occurs [אבן עזרא]. Finally, a different perspective rejects the idea of universal spiritual salvation for the nations, explaining instead that the light refers to the prophet's personal glory, as his name and honor will become famous and revered across the globe [שד״ל].
