שמואל א, פרק כ״ד, פסוק ו׳

In a sudden moment of triumph, an opportunity arises to permanently eliminate a deadly threat. Yet, instead of striking down his pursuer, a profound moral sensitivity awakens within David. He experiences a sharp pang of conscience, feeling deep distress and inner fear over his actions [רד״ק]. This reaction reveals that a person with a pure and whole heart feels immediate shock and regret even after committing a very small wrong [מלבי״ם].

The source of this heavy guilt stems from merely cutting the king's garment. Even minor damage to royal clothing is an act of disrespect toward the crown [ביאור שטיינזלץ]. David reasons that if damaging the king's clothes is unjust, harming his physical body is absolutely forbidden [מלבי״ם]. He fears that God might hold this act against him as a sin, because despite being hunted, he is still obligated to maintain a deep reverence for the king [רד״ק]. Through this heavy guilt, David recognizes that the fear of the monarchy still binds him, and Saul's reign is not yet over [מלבי״ם].

David views his guilty conscience as a direct message from God. While his men argue that God has handed his enemy over for execution, David understands the exact opposite. He realizes that God is the one stirring his heart to feel guilty over a mere piece of cloth, serving as a divine warning not to lay a hand on the king himself [אלשיך].

Harming the king is fundamentally wrong for two main reasons [אברבנאל, אלשיך]. First, Saul is his master. Having once eaten at the royal table, David recognizes an enormous obligation to respect the one who opened his home to him [אלשיך]. Striking one's master is an act of outright treason and rebellion [אברבנאל]. Second, Saul is God's anointed. David's men might claim that God has rejected the current king and that David is now the true anointed leader, but David insists that his pursuer still holds the sacred title [אברבנאל]. Even though David was anointed with sacred anointing oil while Saul was anointed with a simpler balsam oil, Saul's sacred status remains fully intact [אלשיך].

Beyond his personal piety, integrity, and absolute trust that God will remove His enemy naturally when the time is right, David is driven by a forward-looking political motive. Knowing that he will eventually take the throne, he needs to establish a firm precedent of strict respect for royal authority. By sparing his pursuer, he teaches the people that the honor of the crown must never be taken lightly [אברבנאל].
