Going into battle requires preparation and proper equipment, yet on the eve of a major military clash, the Israelites faced a grim reality of absolute technological and military inferiority. The Philistines, who controlled the region, held a strict monopoly on the innovative iron industry. To prevent any chance of rebellion, they systematically removed all ironworkers and blacksmiths from the Land of Israel, or strictly forbade their own craftsmen from living among the Israelites. Their explicit fear was that these artisans would manufacture swords or spears [רש"י, מצודת דוד, רלב"ג, ביאור שטיינזלץ]. Some suggest this absence was an official decree imposed by the Philistine rulers [חומת אנך], while a natural scarcity of iron ore in the land may have also contributed to the problem [רלב"ג].
This harsh reality did not develop overnight. Philistine dominance had plagued the region for many years, dating back to the days of Samson and Eli. Although the prophet Samuel managed to subdue them for a time, during his later years the Philistines returned, setting up governors and reasserting their authority, a situation that persisted into the early days of Saul's reign [רש"י, רד"ק, אברבנאל]. The consequences of this control were felt daily. The Israelites developed a complete dependence on their enemies even for basic agricultural needs. To sharpen or repair everyday farming tools like plows, they were forced to travel down into Philistine territory or make do with simple files because there were no local professionals available [מלבי"ם, רד"ק, אברבנאל].
Militarily, the situation was far more severe. While a few swords from previous eras might have remained in the land, the vast majority of Israelite fighters were forced to rely on simple, improvised weapons such as bows, sticks, slings, and stones [רד"ק, אברבנאל]. As a result, when the day of battle finally arrived, the only individuals equipped with standard weapons were Saul and his son Jonathan [רלב"ג]. Ultimately, this stark contrast between the physical weakness of the Israelites and the immense power of the enemy serves to amplify the magnitude of the upcoming miracle. Facing a massive, well-equipped Philistine army complete with chariots and cavalry, the small, unarmed Israelite force stood as a testament to a clear message of faith. It proves that victory does not depend on military strength or advanced weaponry; salvation belongs to God alone, who delivers those who fear Him and rely on His kindness [רד"ק, אברבנאל].
