David’s journey transitions from a lone fighter to a senior military leader, marked by extraordinary achievements and widespread public support. He began taking on regular military missions and campaigns [מצודת דוד, ביאור שטיינזלץ]. In every task he undertook, he found complete success, leading observers to view his actions as the product of great intellect and wisdom [מצודת ציון]. This consistent record of success, particularly in battles against the Philistines, proved that his abilities extended far beyond individual bravery; he was a deeply reliable figure and a highly capable general [מלבי״ם, ביאור שטיינזלץ].
Recognizing these talents, Saul appointed him as the supreme commander over the army. This elevation in rank was met with overwhelming approval, as David naturally won the hearts of everyone he encountered. The primary approach among commentators highlights a particularly surprising aspect of this public adoration: the reaction of Saul's own servants. These individuals were actually veteran military officers whose entire careers were dedicated to the army. Despite David’s sudden promotion and his new authority over these seasoned professionals, they harbored no jealousy. Instead, they welcomed his leadership graciously and without a trace of resistance.
