The residents of Ziph approach Saul in Gibeah to reveal David's location, repeating a betrayal they had committed once before. They travel to Saul's hometown to inform on David, who is taking refuge in the exact same area where he had previously hidden [מצודת דוד, אברבנאל, ביאור שטיינזלץ]. The motivation behind this repeated act likely stems from the local population's background. As members of the Calebite clan, they lacked sympathy for David. Alternatively, they simply wanted to rid themselves of an uninvited guest who had become a heavy burden on their community [ביאור שטיינזלץ].
Despite their clear intent, the messengers are highly careful in how they deliver this information to the king. They merely state that David is hiding, intentionally avoiding any direct offer to hand him over or any explicit push for Saul to go out and capture him. This cautious phrasing is driven by fear. Saul and David had previously sworn an oath of peace to one another, and David had already proven his innocence. The informants worry that if they actively encourage Saul to break his royal oath, the king might turn his anger toward them and punish them for stirring up conflict.
To protect themselves, they use vague language as a form of insurance. If Saul reacts with anger to their words, they can easily excuse themselves by claiming they only meant to report that David was hiding in the area to ambush the Philistines, the king's enemies. However, if they see that Saul is pleased by the news and eager to restart his pursuit, they can present their report as a helpful tip designed to assist him in finally capturing his rival [חומת אנך].
