King David looks back on his life and military triumphs, recognizing that his success came not from his own natural strength, but from God's providence and protection. God's salvation acted as both a physical and spiritual shield [מצודת דוד, ביאור שטיינזלץ]. This divine assistance goes beyond ordinary bravery and standard weaponry. It is compared to a mortal king gifting his personal royal armor to a favored subject, much like King Saul offering his own uniform to David before the battle with Goliath [אברבנאל]. Furthermore, this protection was never just a temporary defense; it served as a guarantee and pledge for future salvation and total victory over his enemies [אלשיך, צאינה וראינה].
When considering what elevated David to such heights, commentators offer two distinct perspectives on how God interacted with him. One approach suggests that it was God's direct response, His will, and His active help that expanded David's power and made him great [רד״ק, ביאור שטיינזלץ]. However, the primary approach among commentators focuses on the concept of divine humility. In this view, it was God's willingness to lower Himself and watch over a mortal that truly multiplied David's strength. From a military standpoint, God's humble care transformed David's small, modest forces into a mighty power, enabling him to defeat numerous enemies as if he commanded a massive army [מצודת דוד, רד״ק, מצודת ציון, ביאור שטיינזלץ].
This dynamic highlights a profound spiritual principle: wherever God's ultimate greatness is revealed, His humility is also found, demonstrated by His care for human beings who are so far beneath Him [אהבת יהונתן]. More than just benefiting from this divine humility, David absorbed it into his own character [רש״י]. His early years spent as a shepherd, caring for lowly animals, instilled in him the exact humility required to lead the people of Israel [אהבת יהונתן]. As a result, unlike typical warriors who often fall prey to arrogance and aggression after tasting victory, David remained deeply humble and moral despite his tremendous courage and achievements. This enduring humility stands as his true greatness [אברבנאל].
