יחזקאל, פרק י״ח, פסוק ב׳

The generation facing destruction and exile feels a deep, bitter sense of injustice. To express their frustration, the people use a popular proverb about fathers eating unripe, sour fruit. In this saying, the fathers who eat the fruit suffer no harm, but their children's teeth are weakened, making it difficult for them to chew [רש״י, מצודת ציון].

The primary approach among commentators is that this imagery captures the core complaint of the people. They feel that their ancestors sinned heavily yet lived in peace and passed away, while the current generation, who sins less, is left to suffer the harsh punishment of destruction [מצודת דוד, רד״ק, ביאור שטיינזלץ]. This widespread feeling actually grew from the messages of the prophets themselves, who frequently warned the nation that they were suffering because of the terrible sins committed by past kings like Jeroboam and Manasseh [רד״ק].

Believing they were trapped by history, parts of the nation fell into a state of apathy. They assumed there was no reason to worry about the consequences of their own personal actions, thinking their doom was already sealed by the behavior of their ancestors [רש״י]. However, the people completely misunderstood the situation. God's anger and the resulting destruction did not arrive simply because of past mistakes. Rather, the current generation was being punished because they actively chose to continue the corrupt practices of their ancestors. If the children had rejected the sins of past kings, they would not have suffered for those ancient wrongs, and the land would have remained safe [רד״ק].

Looking at this from a broader spiritual perspective, the prophet's challenge to this proverb marks a profound theological shift. Originally, the rule that God punishes children for the sins of their fathers applied strictly to the sin of idol worship, and only when the children actively maintained their parents' destructive habits. In this context, the sour fruit of the proverb represents the worship of false idols. Yet, the prophet arrives with a message that changes everything. He announces that because the urge for idol worship is destined to be removed from the world by the Men of the Great Assembly, the decree of generational punishment will be completely canceled. God declares that this proverb will no longer have any place in Israel, as from now on, every individual will be judged entirely on His or her own actions [מלבי״ם].
