The first external threat to the newly formed Israelite monarchy emerges not by chance, but through divine providence. God orchestrates this crisis to provide King Saul with an opportunity to prove his military capabilities and solidify his leadership in the eyes of the people, especially since he had returned to his home to live as an ordinary citizen [אלשיך].
The aggressor is Nahash, the king of Ammon [ביאור שטיינזלץ]. His name reflects his cruel and wicked nature, acting much like a venomous snake [אברבנאל]. Driven by jealousy over the Israelites crowning their own king, he launches a military campaign. His choice to target the city of Jabesh-gilead is highly deliberate. The residents of this city are close relatives and in-laws of the tribe of Benjamin, King Saul's own tribe. By attacking them, Nahash intends to directly provoke and challenge the new king [מלבי״ם].
The Ammonite king sets up camp and places the city under siege, though he stops short of launching a full-scale assault [מצודת ציון, רלב״ג, ביאור שטיינזלץ]. Gripped by profound fear, the residents of Jabesh-gilead reach out with a desperate plea. They offer to surrender completely, proposing a treaty of peace and submission [ביאור שטיינזלץ, מלבי״ם]. They are willing to pay heavy taxes and even become slaves, asking only that their lives be spared [מצודת דוד, רלב״ג].
Nahash rejects their financial offer. Driven by intense cruelty and a desire to prove that his power cannot be bought, he demands a gruesome condition for any treaty: the gouging out of the right eye of every resident in the city. His primary goal is to humiliate the entire nation of Israel, exposing their weakness and inability to save their own brothers [רלב״ג, אברבנאל].
Beyond the literal cruelty, this demand carries a deeper symbolic weight. Some explain that the right eye represents the nation's military strength, specifically their archers and slingers, or their spiritual leadership as embodied by the Sanhedrin. Others view this encounter as a profound ideological clash. Because the Torah strictly forbids seeking the peace or welfare of the Ammonites, Nahash mocks the Israelites. He demands that they destroy the Torah, which is metaphorically referred to as the right eye, or at the very least, erase the specific commandment that bans an Ammonite from entering God's congregation. Only by compromising their core religious laws would he agree to a peace treaty [אברבנאל, חומת אנך].
