Stepping into the role of a new leader, Saul faces the major challenge of forging a united national army out of fragmented tribes. To understand the true strength of his forces, he gathers the people and conducts a comprehensive census.
The count reveals a massive military force, yet it highlights a distinct division between the general tribes of Israel and the tribe of Judah. The men of Judah are organized and tallied as a completely separate military unit. This distinction is due to their large numbers, their unique abilities, and their geographic distance from the rest of the nation [ביאור שטיינזלץ].
The exact nature of this gathering presents an interesting discussion. The primary approach among commentators is that the army assembled at a specific geographic location with historical roots in the era of the Judges. However, many other commentators understand this detail not as a physical place, but as the clever method used to count the soldiers. Biblical law strictly forbids counting the Israelites directly, warning that a direct census could bring about a deadly plague [חומת אנך, אברבנאל]. To avoid this danger, Saul conducts an indirect count using pottery shards, small stones, or gravel. Each man brought a single stone, and Saul tallied the stones rather than the individuals [רש״י, רד״ק, ביאור שטיינזלץ, אברבנאל]. This interpretation is supported by an ancient Aramaic translation of the Book of Proverbs, which uses a similar term to describe stones fired from a sling [רש״י, רד״ק, אברבנאל].
This early use of simple stones offers a glimpse into Saul's personal financial situation at the dawn of his reign. A fascinating contrast emerges when comparing this event to a later military census, where Saul counts his army using lambs instead of stones. Sages explain that ascending to public leadership brings wealth to the appointed leader. In his early days as a poor man, Saul had to rely on simple stones to number his troops. Later in his reign, having acquired royal wealth, he was able to provide every single soldier with a lamb from his own flocks to complete the census [רש״י, רד״ק, חומת אנך, אברבנאל].
