Achieving true victory over an entrenched enemy requires more than just winning battles; it demands the complete dismantling of their leadership, identity, and capacity to rebuild. The promised triumph over the inhabitants of the land is exactly this kind of total uprooting. The campaign is designed to strike the head first and let the effects filter down to the very last soldier.
The capture of the enemy kings is described as a rare, miraculous event. Typically, monarchs are heavily guarded and are the first to flee a losing battlefield. Yet, God promises to deliver these rulers alive directly into the hands of the Israelites [אור החיים, ביאור יש״ר]. This is a strategic divine plan. Without a monarch, an enemy force entirely loses its ability to rally, organize, and wage war [העמק דבר].
Once the leadership is captured, the next step is the complete erasure of their legacy. Commentators offer several layers to this requirement. On a practical level, it means wiping out the royal bloodlines. Leaving any descendants of kings alive creates a constant risk of future rebellion, whereas eliminating them ensures the enemy cannot quickly appoint a new ruler [ספורנו, העמק דבר]. On a national level, this erasure means the total loss of their identity as a people. They will be stripped of all status, recognition, and memory on the earth [רמב״ן, הטור הארוך, ברכת אשר על התורה]. Furthermore, this serves as an active command forbidding the preservation of the names of these idol worshippers and their false gods [ביאור שטיינזלץ].
The inevitable result of this leadership collapse and loss of national identity is that no opponent will be able to withstand the advance. Stripped of a king to inspire a fighting spirit, the enemy soldiers will completely lose their courage [העמק דבר]. This inability to stand firm applies not just to a single individual, but encompasses entire nations, large families, and even immensely powerful giants like Og, the king of Bashan [לבוש האורה].
The final downfall of these nations will not be characterized by a desperate, drawn-out fight to the death. Instead, the destruction will unfold without any meaningful resistance. The enemies will simply remain in a state of weakness and lowliness until their absolute end [רלב״ג, ברכת אשר על התורה]. This total eradication is an active process carried out directly by the Israelites [אבן עזרא, אבי עזר, ברכת אשר על התורה]. It will not happen in a single moment. The kings and the majority of the population will fall first, while the elimination of the remaining inhabitants will be completed gradually over time [רמב״ן].
