A powerful divine promise of providence, guidance, and historical mission is presented, though commentators are divided on exactly who is receiving this profound calling. Some scholars maintain that God is speaking directly to the prophet Isaiah [רש״י, אבן עזרא, מלבי״ם]. Others suggest the message is directed toward the entire nation of Israel suffering in exile [רד״ק, שד״ל, צאינה וראינה]. A third perspective argues that these words are intended for the Messianic King [מצודת דוד, צוארי שלל, ביאור שטיינזלץ].
God's call is rooted in kindness and righteousness, ensuring that His prophetic promises are true and certain [שד״ל, מצודת דוד]. It is compared to someone calling out to a distant friend because of their virtue, drawing them close [מלבי״ם]. This calling also carries an underlying theme of repentance. The ultimate redemption hinges on the Israelites returning to God; the moment they begin this process of repentance, God will open the gates of mercy for them [צוארי שלל].
The primary approach among commentators is that God offers profound support and protection to His chosen messenger. He provides the strength needed to overcome obstacles and offers a shield against harm, particularly protecting the Israelites from the surrounding nations during their long exile [רד״ק, מצודת דוד, מצודת ציון, אבן עזרא, שד״ל, צאינה וראינה, ביאור שטיינזלץ]. In the context of the prophet, this divine assistance prepares him for his demanding role and ensures he will not fail [מלבי״ם]. Conversely, a unique interpretation suggests that God is not merely offering protection, but speaking of the messenger's very creation. From the moment the prophet was formed, God’s original design was to destine him to bring the people back to their covenant [רש״י].
The core internal purpose of this mission is for the messenger to act as a mediator, guiding the Israelites back to the covenant of the Torah and its Commandments [רש״י, מצודת דוד, מלבי״ם, ביאור שטיינזלץ]. While the Israelites have always been a treasured people, this special status is often hidden during the darkness of exile. Only when redemption arrives will it become universally apparent that they are God's true covenantal partners [שד״ל]. Taking an even broader view, some suggest that the continued existence of all nations across the globe actually depends entirely on this covenant of the Israelites [רד״ק, צאינה וראינה].
Ultimately, this grand mission does not end with the Israelites alone but expands to encompass all of humanity. The goal is to illuminate the eyes of the nations wandering in darkness, leading them to recognize the unity of God and walk by the light of the Torah emerging from Zion. This spiritual awakening will usher in global peace and inspire the nations of the world to observe the Seven Noahide Laws [מלבי״ם, מצודת דוד, רד״ק, צאינה וראינה]. As this unfolds, the Israelites will become a beacon of glory and praise among all peoples [שד״ל]. However, a completely different interpretation argues that this illumination is meant strictly internally; rather than referring to the nations of the world, it refers to the individual tribes of Israel, since each tribe can independently be considered its own nation [רש״י].
