דברים, פרק ב׳, פסוק ל״ג

The defeat of the Amorite king Sihon was not merely a military triumph, but a moment of direct divine intervention. Rather than forcing the Israelites to fight through heavily fortified walls, God drew the enemy out into the open battlefield. By delivering Sihon outside his stronghold of Heshbon, God spared the Israelites from a long, exhausting siege. This act of providence ensured that the cities were not destroyed in combat, allowing the Israelites to inherit them completely intact and fully built [אלשיך, מלבי״ם]. With the enemy exposed, the Israelites struck a decisive and final blow [ביאור שטיינזלץ].

The complete destruction of Sihon's forces included not just the general population, but specifically his sons. While it might seem unnecessary to single them out since they were part of the nation, they are highlighted because they were prominent leaders and military commanders in their own right [העמק דבר, ביאור שטיינזלץ]. The battle unfolded in stages. Sihon initially went out to fight alone and was struck down. Only after his defeat did his sons arrive at the battlefield to lead the army, where they met the exact same fate [העמק דבר].

A closer look at the historical record reveals a unique dynamic within Sihon's family and defenses. Although Sihon had many sons who died in the war, one particular son stood out as a powerful warrior, matching his father's strength [רש״י, גור אריה, שפתי חכמים, משכיל לדוד]. Some suggest this specific son was even stronger than Sihon himself [שפתי כהן]. A completely different perspective shifts the focus from Sihon's family to the physical fortifications of the battle. In this view, the historical account hints at the concept of construction, suggesting that while the enemies heavily built up and reinforced their defensive walls, the Israelites ultimately shattered them and brought them into submission [שפתי כהן].
