ירמיהו, פרק מ״ח, פסוק מ״ב

The downfall of Moab represents more than just a military loss on the battlefield; it is the complete erasure of a national identity. The nation brought this absolute ruin upon itself not through conventional warfare, but through profound arrogance and mockery directed toward heaven.

As a result of their actions, Moab is destined to completely cease existing as a nation [מצודת דוד]. When a typical nation fights and falls in battle, its memory is often preserved by future generations. Moab, however, fell in disgrace like women, meaning they will be entirely wiped from historical memory and no longer considered a people at all [מלבי״ם].

The root cause of this unusual and total defeat lies in their extreme boasting and pride [ביאור שטיינזלץ]. Their primary offense was not engaging in actual physical combat against the Israelites, but rather relying on relentless provocation and cruel mockery [ביאור שטיינזלץ]. This arrogance reached its peak during the exile of the Israelites. In that vulnerable time, the people of Moab spoke with deep disrespect toward heaven, openly claiming that God lacked the power to save or help His own people [מצודת דוד]. Ultimately, it was this bold arrogance that sealed their fate and led to their total annihilation [מלבי״ם].
