ירמיהו, פרק ה׳, פסוק א׳

God is willing to forgive an entire city for the sake of a single worthy individual. A striking contrast is drawn between the busy public spaces of Jerusalem and the complete moral emptiness of its society. God issues a call to wander through the city, to look closely and pay careful attention to how people act, hoping to find just one person whose merit could save the entire public [מצודת ציון, רד״ק, שטיינזלץ].

This search must cover all areas: the narrow alleys tucked behind houses, as well as the wide markets and large public gathering spaces [מלבי״ם, מצודת ציון]. The goal is not merely to find a human being, but to discover an honorable, great person defined by good deeds [מצודת ציון, רד״ק, שטיינזלץ]. This individual must possess two specific qualities that represent total moral completeness: doing justice, which reflects the duties between people, and seeking faith, which reflects the duties toward God [מלבי״ם, חומת אנך]. The primary approach among commentators is that if even one such person is found, God will forgive all of Jerusalem.

However, this raises a historical and conceptual question. Is it possible that in Jerusalem, a city famous for its wisdom, priests, and prophets, not a single righteous person remained? This question grows stronger considering that other biblical accounts describe devoted followers of God who were killed during the city's destruction.

Commentators address this reality in several ways, painting different pictures of the social state of the city. One approach suggests that righteous people did exist in Jerusalem, but they were forced to hide in their homes out of fear of the wicked. For this reason, the search is directed specifically at the streets and public squares, because out in the open, the righteous were nowhere to be found [אביו של הרד״ק]. A different view argues that there were truly no righteous people left at all. According to this perspective, the devoted individuals mentioned elsewhere were actually wicked and deserving of death, but their death at the hands of the enemy served as an atonement, turning them into righteous people only after the fact [חז ל המובאים ברד״ק].

Another interpretation suggests that the streets were indeed full of people, but the issue lay in their reaction to justice. Whenever a judge or a prophet appeared in public to demand faith and fair conduct, the masses would flee and hide in their homes to avoid facing the criticism. As a result, precisely at the moment justice was being pursued, the streets would completely empty out [מלבי״ם]. Finally, another approach argues against the idea that the righteous were simply hiding, noting that true believers should be able to protect their generation even from indoors. According to this view, there were certainly people of truth and faith in Jerusalem. The problem was the absence of a true leader. The righteous who lived there were submissive and lacked any real influence. God promises that if even one brave public figure steps forward to enforce justice and confront the criminals in the city streets, His forgiveness will be granted to the entire city in the merit of that single leader [אברבנאל].
