שמואל א, פרק ל״א, פסוק ד׳

In the final moments of a dramatic battle, Saul, the King of Israel, faces a grim reality. He realizes that his defeat is absolute and that capture by the enemy is unavoidable. Forced into a tragic corner, he decides to end his life rather than fall into the hands of the Philistines. He commands his armor-bearer to draw his sword and deliver a precise, fatal blow, hoping for a quick death without unnecessary suffering [מצודת ציון, מצודת דוד, ביאור שטיינזלץ].

This desperate request is driven by a heavy fear of the enemy's cruelty. Saul knows the Philistines will seek bitter revenge for the heavy blows he dealt them in the past. If captured alive, they would not simply kill him; they would inflict multiple painful wounds, keeping him alive just long enough to torture, mock, and humiliate him before his death [רד״ק, רלב״ג, מצודת דוד, מצודת ציון]. [מלבי״ם] explains the king's exact calculation. Had the Philistines intended only to torture him while leaving him alive, Saul would have chosen a life of pain over ending his own life. Similarly, if they planned to kill him immediately, taking his own life would not be justified. However, knowing with certainty that they would subject him to agonizing humiliation and then kill him anyway, he prefers a swift death at the hands of a loyal friend.

Despite the direct order, the armor-bearer refuses. He is paralyzed by a profound fear, primarily a fear of God, as he recoils from the severe sin of striking down God's anointed king [מצודת דוד, ביאור שטיינזלץ]. Furthermore, as a terrified young man, he is psychologically incapable of bringing himself to kill his leader, regardless of his absolute loyalty [ביאור שטיינזלץ].

Left with no alternative, Saul takes matters into his own hands. He positions his sword and falls upon it to end his life [מצודת דוד, ביאור שטיינזלץ]. However, a question arises regarding whether this act killed him instantly, especially given a later account where an Amalekite youth claims to David that he dealt the king's final blow. One possibility is that the young Amalekite simply lies to win favor with David, knowing the historic tension between David and Saul [רלב״ג]. Yet, the primary approach among commentators is that falling on a sword is a difficult method that does not guarantee an immediate death. Saul is mortally wounded and in agony, but still clinging to life. The Amalekite youth, stumbling upon the scene shortly after, is the one who ultimately finishes the grim task and ends the king's life [רלב״ג, מלבי״ם, ביאור שטיינזלץ].
