שופטים, פרק י׳, פסוק ח׳

Following the death of their leader, the Israelites are abruptly plunged into a period of severe vulnerability. The Ammonites launch a sudden, crushing, and prolonged assault against them. Though Ammon is a relatively small kingdom, their forces are highly organized. This structural advantage allows them to overpower the Israelites and conquer the neighboring region of Gilead [ביאור שטיינזלץ]. The impact of their invasion is not a simple military defeat; it is a violent, shattering blow that completely fractures the targeted communities [מצודת ציון, ביאור שטיינזלץ]. Notably, the textual description of this shattering blow marks the exact midpoint of the Book of Judges, serving as a structural and thematic turning point for the era [מנחת שי].

A complex picture emerges regarding the timeline of this suffering, as the crisis is said to happen during a specific single year while simultaneously lasting for eighteen years. It is generally agreed that the specific year in question is the year the judge Yair died [רש"י, מצודת דוד]. To resolve the overlapping timeframes, one approach suggests that the oppression simply begins in that fateful year and extends forward for the next eighteen years [רד"ק].

However, a deeper perspective reveals that this dual timeframe highlights the highly unusual nature of the Ammonite conquest. Most invasions unfold gradually, with the enemy slowly gaining ground over time. In this case, the punishment is immediate and absolute. The full, devastating force of the attack lands all at once in that very first year, and this extreme level of severity is maintained without any relief for eighteen consecutive years [מצודת דוד, מלבי"ם].

Despite the intense scale of the attack, the suffering does not engulf the entire nation. The invasion is highly localized, targeting only the Israelites living on the eastern side of the Jordan River. These eastern groups, consisting of the tribes of Reuben, Gad, and half the tribe of Manasseh, bear the absolute brunt of the assault because they are the immediate geographical neighbors of the Ammonite kingdom [רש"י, מצודת דוד, ביאור שטיינזלץ].
