A prophecy of doom paints a bleak picture of a destructive campaign moving relentlessly from city to city. The fall of one stronghold serves as a terrifying warning to its neighbors, ultimately leaving the survivors homeless and completely stripped of their leadership. The impending disaster first targets the Moabite city of Heshbon, urging its people to wail over the ruin of Ai. This is not the ancient Canaanite city, but rather a fortified stronghold in the land of Ammon. The enemy's conquest swept through Ammon first, crushing this powerful city. The collapse of such a mighty fortress signals imminent doom for nearby Heshbon. The enemy forces are advancing, and the realization sets in that if a stronghold like Ai could not withstand the assault, Heshbon has no hope of survival [רד״ק, מצודת דוד, מלבי״ם].
The devastation then spills over into the surrounding rural towns and small farming villages that border the Ammonite capital [רד״ק, מלבי״ם]. The people living in these outskirts are called to cry out, dress in mourning clothes, and weep. They understand that their great capital city is destined to fall, meaning they will no longer have any safe haven to run to for protection [רד״ק].
Stripped of their homes and safety, the survivors are forced to flee, wandering aimlessly and helplessly in a state of total vulnerability [מצודת ציון]. The primary approach among commentators is that they seek refuge among simple stone fences used to pen sheep. Because their houses are destroyed [מלבי״ם] and the fortified city walls can no longer offer defense, the people are reduced to hiding in open pastures among agricultural enclosures [רד״ק, מצודת דוד, ביאור שטיינזלץ]. Others view this wandering among the sheep pens as the ultimate display of disgrace and humiliation, with the survivors left to wallow in the dirt and dung of the flocks. Alternatively, based on the Aramaic translation, this wandering refers to the people huddling together in panicked, disorganized bands rather than physical fences [רש״י].
The despair reaches its peak as the nation is entirely stripped of its leadership, dragged away into exile. Commentators disagree on the exact nature of this exiled leader. Some maintain that it refers to the flesh-and-blood Ammonite monarch who ruled from the capital [רד״ק]. Others argue that it refers to the national Ammonite idol, a statue crafted from silver and gold, which the invading army carries off as plunder [מצודת דוד]. In either case, the result is the same: the central figure of authority—whether a human king or a revered idol—is taken away into captivity, alongside the entire political and spiritual leadership of priests and officials, leaving the nation completely broken and abandoned.
