The climax of Dinah's abduction culminates in a moment where calculated planning, brotherly devotion, and explosive rage merge into an unprecedented act of retaliation. The timing of this strike is carefully chosen to occur on the third day following the mass circumcision of the city's inhabitants. The primary approach among commentators is that the third day marks the peak of physical pain and bodily weakness for the circumcised men [רד״ק, רבנו בחיי, תורה תמימה]. However, others suggest that the physical danger and pain might actually be greatest during the first few days. Instead, the brothers waited until the third day because an entire city could not possibly undergo the procedure in a single day. Only by the third day was the mass circumcision complete, leaving the entire population simultaneously incapacitated [טור, הדר זקנים, דעת זקנים].
Beyond the physical agony, many commentators uncover a psychological layer to the men's suffering. Their pain included deep heartache and regret. The men of Shechem realized that their circumcision would render them despised by neighboring nations. Fueled by this remorse, they conspired to gather and kill Jacob's family as soon as they recovered. Dinah, who was still held captive in Shechem's house, overheard this plot and smuggled a warning to her brothers. In this light, the brothers' assault was not merely an act of vengeance, but a preemptive strike of self-defense [הכתב והקבלה, מלבי״ם, רא״ש, חזקוני, הדר זקנים].
The narrative emphasizes that the attackers were Simeon and Levi, sons of Jacob. Highlighting their lineage points to a tragic contrast: although they were his sons, they acted like strangers, taking matters into their own hands without seeking their father's counsel [רש״י, מזרחי, גור אריה, ביאור יש״ר]. Despite operating as a pair, each was driven by a distinctly different internal motive. One acted out of human zeal for family honor, while the other was motivated by a pure zeal for God [העמק דבר]. They alone took on this mission because the other brothers had various reasons to avoid involvement, whether due to their personal status or their roles in past family events [שפתי כהן]. Furthermore, they are specifically identified as Dinah's brothers because they were the only ones truly willing to risk their lives to save her, thereby proving their profound brotherly bond [רש״י, מזרחי, רד״ק, בכור שור].
Describing the brothers as men reveals a surprising detail about their age. Simeon and Levi were young teenagers at the time, merely thirteen years old. Commentators deduce from this that thirteen is the age at which a youth is considered a man, fully responsible for his actions [רבנו בחיי, תורה תמימה, הכתב והקבלה]. The question naturally arises as to how two young boys could subdue an entire city. One perspective suggests that the residents of the city were completely complacent, relying heavily on their newly formed peace treaty and never imagining they would be attacked [רשב״ם, ביאור יש״ר, שטיינזלץ]. Another perspective attributes the overwhelming confidence to Simeon and Levi themselves. They entered the city with absolute certainty, moving as if they were a massive army, relying entirely on the spiritual merit of their father Jacob or the prayers of Abraham [רש״י, כלי יקר, רד״ק].
The lethal outcome, resulting in the death of all the males, raises profound moral questions regarding the collective punishment of the city. Commentators offer several justifications for this severe action. First, the residents were not innocent bystanders; their agreement to undergo circumcision was driven by sheer greed, rooted in a calculated plot to plunder Jacob's wealth [ספורנו, חזקוני, מלבי״ם]. Second, under the universal laws given to Noah, a society is obligated to establish a justice system to punish crimes like kidnapping and robbery. Because the townsmen witnessed Shechem abduct Dinah and chose to remain silent, they bore a collective guilt that made them liable for death [אור החיים, מלבי״ם, ברטנורא, שפתי כהן]. Additionally, because the residents were actively plotting to murder Jacob's family, they were legally classified as lethal pursuers [אור החיים]. The slaughter ultimately encompassed not only permanent residents but also visiting merchants and guests, which explains why Jacob was so deeply terrified of retaliation from neighboring cities [קונטרס חיבה יתירה]. Ultimately, while the brothers' initial motive was pure—aimed at protecting their sister's honor and establishing a necessary deterrence to prevent their family from being trampled—the method they employed was a mass slaughter. This extreme measure was a blatant overstepping of the boundaries of justice, which is why it later drew Jacob's sharp and unyielding criticism [רש ר הירש].
