A military standoff often comes with bold threats, but true wisdom lies in recognizing the unpredictable nature of war. In a sharp response to his enemy, Ben-Hadad, the king of Israel instructs messengers to deliver a clever proverb warning against premature arrogance [מצודת דוד, רלב״ג, רד״ק]. The primary approach among commentators is that this message contrasts two distinct moments in a soldier's journey. It compares a warrior just strapping on his weapons to one who is taking them off. The soldier preparing for combat faces the absolute unknown, while the one removing his gear has already returned home in victory [רש״י, מצודת דוד, ביאור שטיינזלץ].
The core message is a timeless warning against boasting about a success that has not yet happened [מצודת ציון, ביאור שטיינזלץ]. Even a powerful king commanding a massive military force cannot predict how a battle will unfold. History is filled with instances where a small, outmanned army completely defeats a vast and mighty force [רלב״ג, אברבנאל].
Beyond the basic reality of uncertainty, this proverb touches on a deeper psychological and strategic truth. When a fighter marches into battle assuming the victory is already his, he is actually more likely to fail. Overconfidence breeds carelessness, causing a commander to neglect proper planning and strategy. At the same time, extreme arrogance and harsh demands back the opposing side into a corner, forcing them to fight fiercely for their very survival. By sharing this insight, the king of Israel hints to Ben-Hadad that he made a severe miscalculation. Given the unpredictable nature of war, Ben-Hadad should have been satisfied with the initial offer of peace and surrender. Instead, his excessive demands provoked a desperate conflict with an entirely unknown outcome [מלבי״ם].
