In the midst of a crucial military campaign, the Israelite army experiences a dramatic reversal of fortune. The fighters transition from a state of vulnerability to an intense pursuit of their enemy, driven by a strict royal decree designed to maintain their momentum at all costs. There are two primary approaches regarding the physical and emotional state of the soldiers during this shift. One view suggests they were under severe distress, pressure, and hunger. Exhausted by Saul's relentless push, they fought out of sheer necessity rather than a free desire for liberation [מלבי״ם, רלב״ג, רד״ק, מנחת שי, ביאור שטיינזלץ]. Conversely, another perspective views their state as one of active engagement and renewed courage. Having initially hidden in caves, the soldiers witnessed God's salvation, emerged from their hiding places, and charged the enemy with fresh energy and willingness [רש״י, מצודת דוד, אלשיך, אברבנאל].
To ensure the pursuit would not lose its momentum, Saul bound the army with a severe declaration. The primary approach among commentators is that this was a formal oath or curse, though it also reflects Saul's absolute will and unyielding determination [אברבנאל]. Leveraging his authority, Saul feared that if the soldiers paused to rest and prepare meals, the Philistines would seize the opportunity to regroup and launch a counterattack. A halt would forfeit the critical advantage gained through swift, decisive action [ביאור שטיינזלץ, מצודת דוד]. He chose to enforce this through a solemn oath rather than a standard royal command because a king cannot practically execute an entire nation for disobeying an order. A severe oath, however, carried a spiritual weight that would deter the fighters from abandoning the pursuit and compel them to continue the battle [ראשון לציון].
The oath explicitly forbade the consumption of food. Commentators agree that the specific restriction against eating bread served as a broad category encompassing all food and drink. It is possible that Saul originally intended only to ban formal, time-consuming meals that would delay the army, while still allowing for the quick consumption of fruit to maintain stamina. Alternatively, this may have been a complete, formal fast, a practice common during times of national distress [מלבי״ם]. In practice, the people adopted the most extreme interpretation of the decree. They refused to even taste the food, defining a taste as placing a minimal amount of food in the mouth without swallowing [מצודת ציון]. Although merely tasting food is not typically classified as eating, and normally neither requires a blessing nor breaks a fast, the soldiers completely avoided it, accepting the prohibition in its absolute strictest sense [מלבי״ם, ראשון לציון].
Ultimately, this extreme restriction led to severe exhaustion among the ranks. Jonathan, who was unaware of the oath and had eaten some honey, openly criticized his father's strategy. He argued that withholding food had deeply troubled the army. Had the soldiers been allowed to eat from the captured spoils of the enemy, they would have drawn renewed strength, enabling them to strike the Philistines with far greater force rather than wasting away from the fast [רלב״ג, אלשיך].
