שמואל א, פרק י״ד, פסוק כ״ט

During the heat of battle, a leader's decisions can sometimes hinder the very victory they seek to achieve. Jonathan offers a sharp critique of the fasting decree issued by his father, Saul, exposing the negative impact it had on the army's performance. Saul's original intention in forbidding food was likely practical. He wanted to prevent the soldiers from stopping to eat so they could maintain a continuous, relentless pursuit of the enemy. However, Jonathan argues that this decision was a grave mistake that achieved the exact opposite result, ultimately harming the Israelites' chances of a complete victory [רש״י, מלבי״ם].

Jonathan observes that his father brought ruin and confusion to the nation. The disruption caused by the fast left the fighters disoriented, much like how stirred mud clouds the clarity of pristine water [רש״י, מצודת ציון, ביאור שטיינזלץ]. To prove his point, Jonathan relies on his own physical experience. Exhausted and suffering from severe hunger, he had been in a state of extreme weakness. Yet, simply tasting a small amount of honey was enough to instantly renew his energy and bring the light back to his eyes [מצודת ציון, מלבי״ם]. His personal recovery serves as clear evidence for his broader argument. If the tired soldiers had been allowed to eat, their physical strength would have been restored, and their success on the battlefield would have been far greater and much more effective.
