The prophecy of destruction directed at the nation of Moab opens with a harsh cry of wailing and lamentation [מצודת דוד, מצודת ציון]. From the outset, God is deliberately introduced as the God of Israel. This specific title highlights that God is bringing ruin upon Moab as direct retribution for the deep distress and suffering they inflicted upon the Israelites [רד״ק, מלבי״ם, אברבנאל]. While other invading nations attacked Jerusalem seeking material wealth like silver and gold, Moab’s hostility was uniquely directed against God and His teachings. Driven by a desire for revenge against the biblical law that forbids a Moabite from joining the assembly of God, they seized the Torah scroll and publicly disgraced it [חומת אנך].
The impending doom is detailed through the specific Moabite cities destined to fall to the enemy, illustrating the total collapse of their national security. Among these targets are Nebo, Kiriathaim, and Misgab [מצודת ציון]. Kiriathaim, whose name hints at a paired structure, was known for possessing two prominent towers [רד״ק]. Because it was a heavily fortified stronghold that felt entirely secure against any threat, its sudden capture resulted in profound shame, disgrace, and the bitter disappointment of a shattered defense [אברבנאל, ביאור שטיינזלץ, מצודת דוד].
Similarly, the primary approach among commentators identifies Misgab as a specific city [רש״י, מצודת ציון, רד״ק]. True to its name, it was situated on high ground and served as a highly protected safe haven for the region. When a fortress of such immense security falls, the ultimate refuge of Moab is broken [רד״ק, אברבנאל]. Consequently, its destruction is characterized by overwhelming fear, brokenness, and absolute ruin [מצודת ציון, ביאור שטיינזלץ].
