דברים, פרק ח׳, פסוק כ׳

The right to live in the Land of Israel is strictly tied to following God's path, and abandoning this way of life brings severe, unavoidable consequences. This reality serves as a conceptual conclusion to the broader narrative, perfectly mirroring its beginning [רשב״ם]. While early promises guarantee the land as a reward for obedience, the ultimate outcomes—whether for good or bad—only arrive at the very end of the journey [אבן עזרא]. This dynamic acts as a basic condition for survival [ביאור שטיינזלץ], pointing toward a distant future in the same way a heel is located at the very end of the human body [שפתי כהן].

The comparison to the destruction of other nations is highly deliberate, representing a total loss of any physical foothold or presence in the land [העמק דבר]. The punishment operates on a principle of exact justice: those who choose to act like the surrounding nations will ultimately be destroyed exactly like them [קיצור בעל הטורים]. Furthermore, simple logic dictates this outcome. If the native Canaanites were removed from the land despite never being strictly commanded against idolatry, the Israelites will certainly face destruction if they sin. Their downfall would be entirely justified and proper [שפתי כהן], leaving the land completely desolate without a single person passing through [העמק דבר].

However, this destruction does not happen overnight. Just as the blessings for keeping the Commandments often arrive slowly, the punishment for disobedience is also delayed. If the consequences of sin were immediate, obedience would require no moral effort, and rebellion would simply be madness. Because the punishment unfolds in unseen stages, severe warnings are necessary to remind people of realities that human nature naturally tends to forget [רש״ר הירש].

The root of this downfall is a gradual distancing from God. It begins with simple ingratitude, such as failing to thank God for the food and the land He provided [ספורנו]. Forgetting God's constant care then leads to the abandonment of Torah study. This neglect is the deepest and most central cause of the land's total ruin, even more destructive than the sins of idolatry themselves [העמק דבר]. Ultimately, the refusal to listen to God results in a profound spiritual tragedy that accompanies the physical collapse. By failing to heed His voice, the nation will eventually lose the gifts of prophecy and divine inspiration. They will be left in exile, completely unable to hear the life-giving voice of God [שפתי כהן].
