A pivotal shift in leadership occurred when the Israelites finally united to crown David, an event that took place during a later period [מלבי״ם, ביאור שטיינזלץ]. This massive gathering occurred after David had already been ruling exclusively over the tribe of Judah [מצודת דוד]. The leaders of the armed and fully equipped military forces [מצודת דוד, מצודת ציון] traveled to meet David in the city of Hebron [מצודת דוד, מלבי״ם, ביאור שטיינזלץ].
As the troops assembled, detailed counts of the soldiers were presented. Perspectives differ on how these figures were tallied. One approach suggests that each individual tribe conducted its own separate calculation of its men [מצודת דוד]. Another view maintains that the military commanders handed over the data directly, with each group leader personally reporting the exact count of his soldiers to David [מלבי״ם].
The primary goal of this assembly was to officially transfer the royal power from the sons of Saul directly to David, establishing him as the king over all the Israelites [רש״י, מצודת דוד]. This monumental shift in leadership was the direct fulfillment of the will of God, bringing to life the prophecy He had spoken long before through His servant Samuel [רלב״ג, ביאור שטיינזלץ].
