יחזקאל, פרק ג׳, פסוק כ״א

A prophet carries a heavy burden, standing as a watchman not only for those who have lost their way, but also for those who walk an upright path. The duty to guide extends to the righteous, ensuring they maintain their good conduct and avoid sudden pitfalls. A successful intervention carries a double benefit, positively impacting both the person receiving the warning and the one delivering it.

The focus of this guidance is a person who already has an established history of good behavior [רד״ק]. It might seem unnecessary to caution someone deeply committed to doing what is right, but commentators offer two reasons for this intervention. On one hand, a person with a strong record of good deeds might become overly confident, leading them to entertain thoughts of wrongdoing. A timely warning prevents these thoughts from becoming actions [מצודת דוד]. On the other hand, their elevated spiritual status requires a higher standard of care. They must be cautioned against committing even a minor, accidental offense, because an unintentional mistake by someone of such high standing is judged as severely as a deliberate act [מלבי״ם].

When confronted with a warning, the righteous person listens and refuses to abandon their proper path [רד״ק]. Because of their deeply ingrained good character, they are naturally inclined to accept this kind of guidance [שטיינזלץ, מלבי״ם]. Even if a brief desire to do wrong had crossed their mind, heeding the warning stops them in their tracks, ultimately saving them [מצודת דוד]. Their life is preserved simply because they took care to listen and respond to the prophet's words.

This interaction rewards the messenger as well. By speaking up, the prophet saves his own life. Had he remained silent, the righteous person might have acted on a bad impulse and perished as a result, and the prophet would have been held directly responsible for that tragic loss [מצודת דוד].
