The path to national and spiritual redemption is not a miraculous, unconditional event, but a process entirely dependent on moral and religious repair. The rescue of the city and its people rests on two pillars: true justice and acts of faith. This deliverance—whether understood as a historical rescue from distress, such as the salvation from Sennacherib [שד״ל, אבן עזרא], or as a spiritual cleansing from sin [רש״י]—requires a firm foundation of justice. The primary approach among commentators is that this condition is met only when honest individuals rise to execute fair judgment, treating the rich and the poor equally [רש״י, רד״ק, מצודת דוד, שטיינזלץ, צאינה וראינה]. This aligns with the historical reality of King Hezekiah's reign, during which corrupt officials were removed and replaced with righteous judges [שד״ל]. Another perspective suggests that justice here is not a human action, but the city's inherent legal right. Because the city was once the head of all nations and was later reduced to a mockery, it is legally entitled to be redeemed by strict justice [אהבת יהונתן].
Regarding the identity of the people involved in this redemption, there are three main perspectives. Some maintain that these are individuals returning to God in repentance [רש״י, אבן עזרא]. Others view them as physical exiles who will eventually journey back to the land [רד״ק, מצודת דוד, שטיינזלץ]. A third approach suggests that the concept simply refers to the current inhabitants of the city, independent of any process of repentance or return from exile [שד״ל].
The restoration of these people is deeply intertwined with acts of charity and righteousness. On a practical level, the physical act of giving charity is seen as the vital key to gathering the exiles and rebuilding the city [מצודת דוד, צאינה וראינה, נחל שורק]. Charity possesses this redemptive power because it serves as the ultimate test of a person's faith. Just as a merchant examines a single sample to determine the quality of an entire shipment, parting with one's wealth—an act that seemingly diminishes personal property—demonstrates an absolute, underlying trust in God [אדרת אליהו]. From another angle, this righteousness is viewed not as a human deed, but as divine grace. While the city itself might be redeemed through strict justice, the returning people are not inherently worthy on their own merit. Their redemption is accomplished solely through God's mercy, acting as a form of divine charity [אהבת יהונתן]. This dynamic is illustrated by a legal parable: redeeming a captive for the first time is a strict legal obligation, representing justice. However, if that person is taken captive a second time, there is no legal mandate to save them; a second rescue is performed entirely beyond the letter of the law, as an act of pure grace [צוארי שלל].
The distinct use of the concepts of justice and righteousness also highlights a contrast between the residents of Jerusalem and the inhabitants of the surrounding towns. As a bustling commercial center, Jerusalem's primary failures were interpersonal injustices, necessitating a repair focused on social justice. In contrast, the rest of the region struggled primarily with their direct relationship with God, such as flaws in prayer and sacrifices. Their correction requires righteousness, a concept representing the proper alignment of actions between humanity and the Creator [מלבי״ם]. On a deeper, mystical level, this entire redemption describes an elevated spiritual process. The city symbolizes the Divine Presence, which is redeemed by God Himself through the attribute of justice. Ultimately, the exiles will return to the land not merely for their own benefit, but for the sake of the Divine Presence, guided by God's boundless mercy and grace [נחל שורק, חומת אנך].
