שמואל א, פרק י״ז, פסוק נ״ו

King Saul issues a direct command to Avner, instructing him to investigate the background and origins of David [ביאור שטיינזלץ]. While David is still just a youth [מצודת ציון], the specific way he is described at this moment is highly intentional and carries a deep sense of respect.

Previously, in their private conversations, Saul and Avner referred to David using a basic term meant for a young servant or an apprentice who had not yet achieved any real standing. Now, however, Saul is careful to protect David's dignity. When issuing his public order to Avner, the king deliberately chooses a more elevated and respectful title for the young man, ensuring that David is honored in the eyes of the people [מלבי״ם].
