שמואל א, פרק י״ט, פסוק ו׳

A father's response to his son marks a distinct turning point in a troubled relationship. Saul does not merely listen to Jonathan's defense of David on a surface level. Instead, he deeply absorbs the message, fully understanding the truth of his son's reasoning [חומת אנך].

Moved by this realization, Saul takes a solemn oath. He makes this vow deliberately, using it as a tool to suppress and conquer the destructive desire within him that has been driving him to harm David [חומת אנך]. His oath serves as a clear and absolute promise that David will not be put to death [ביאור שטיינזלץ]. This is a comprehensive commitment, ensuring that David will not be killed either by Saul's own hands or by any messengers sent on his behalf [חומת אנך].

As a result of this vow, Saul completely removes the thought of killing David from his mind. With the deadly intention gone, the dynamic between the two men is restored, returning to the peaceful state they had shared in the past [מלבי״ם].
