שמואל א, פרק י״ז, פסוק מ״ט

The climax of the confrontation arrives in a sudden motion, as a simple shepherd's tool overcomes a heavily armored warrior. Reaching into his bag where the stones were kept [מצודת דוד, ביאור שטיינזלץ], David hurls a stone with tremendous force using his sling [מצודת ציון, ביאור שטיינזלץ]. The projectile finds its mark, striking the giant directly on the forehead and sinking deep into his skull [רד״ק, מצודת ציון, ביאור שטיינזלץ].

The physics of a stone penetrating a thick copper helmet presents an interesting question. One approach suggests the stone simply found a tiny, exposed gap in the armor that was left unprotected [רלב״ג, רד״ק, ביאור שטיינזלץ]. Another view proposes a miraculous event, where God caused the relatively soft stone to pierce directly through the hard metal [מצודת דוד, רד״ק]. A third tradition offers a different sequence of events. Earlier in the confrontation, when the Philistine boasted about leaving his opponent for the birds of the sky, he tilted his head upward. This motion caused his helmet to slide backward, leaving his forehead completely exposed [רד״ק]. Regardless of the exact mechanics, the absolute precision of the strike was entirely guided by God's careful providence [רד״ק, מלבי״ם].

Following the fatal blow, the massive warrior collapses face-first into the dirt. This forward fall is unusual, as a powerful strike to the front of the head would naturally throw a person backward. Some explain this through natural means, noting that he simply lost his balance [ביאור שטיינזלץ], or that the severe trauma from the deeply embedded stone caused him to faint and crumple forward under his own immense weight [מלבי״ם]. Others view the forward collapse as a deliberate miracle designed to assist David. By falling forward rather than backward, the giant's body was brought closer, saving David the effort of walking the full length of his towering height to finish the battle [רש״י].

Beyond the physical mechanics, this face-first fall carries deep symbolic weight. It served to bury the very mouth that had just cursed and blasphemed God directly into the dust, while simultaneously crushing the idolatrous image that the warrior wore over his heart [רד״ק].
