Saul responds with deep gratitude to the people of Ziph after they offer to hand David over to him. Recognizing their loyalty, he blesses them and asks God to reward them for delivering such crucial information about David's whereabouts [מצודת דוד].
Saul explains that this blessing is a direct response to the compassion they have shown him. Their compassion is not merely an emotion, but rather the active choice to reveal a closely guarded secret. By stepping forward, the people of Ziph prove that they share in Saul's pain and are fully committed to his cause [אברבנאל].
