ירמיהו, פרק ל״א, פסוק ל׳

A time is coming when the understanding of personal responsibility and justice will undergo a profound shift. For a long time, the prevailing thought has been that the exile stretches on due to the mistakes of past generations. Eventually, however, the children will awaken and completely change this mindset [ביאור שטיינזלץ].

The reality of justice will transform so that every individual will be held accountable strictly for their own actions. Children will no longer carry the burden or face the consequences of their parents' wrongdoing. This principle is brought to life through a simple image from nature: when someone eats sour, unripe grapes, only the person eating them feels the physical effect on their own teeth. The teeth of their children remain completely unaffected. The system of justice will work in exactly the same way [מצודת דוד].

There is a practical reason behind this future shift. In that time, the human urge to do evil will no longer overpower people or push them to commit severe wrongs. Because of this inner change, children will not repeat or hold onto the destructive habits of their parents. Since they will no longer follow in those footsteps, a reality where a child is punished for a parent's sin simply will not exist [מצודת דוד].
