שמואל א, פרק כ״א, פסוק ב׳

After parting from Jonathan, David travels to Nob, the religious center of the era. This city housed the priests, the remnants of the Tabernacle of Shiloh, and the Ark of God. His purpose is to pray, bow before God, and seek His counsel before setting out on his journey [אברבנאל, ביאור שטיינזלץ].

Upon David's arrival, Ahimelech the priest reacts with intense emotion, a response understood in two complementary ways. On one level, it is seen as physical urgency, with Ahimelech hurrying out to greet David [מצודת דוד, רד״ק]. This quick movement is driven by excitement, as it is highly unusual for high-ranking ministers and nobles to visit this location [ביאור שטיינזלץ]. At the same time, his reaction is understood as genuine fear and anxiety, sparked by the surprising sight of David arriving completely by himself [רד״ק, אברבנאל].

This alarm prompts Ahimelech to question David about his solitary state. The primary approach among commentators is that Ahimelech's astonishment stems from a stark breach of protocol. It is entirely inappropriate and uncharacteristic for a prominent minister of Israel, who is also the king's son-in-law, to travel without a customary escort. Furthermore, his solitary appearance presents a logical puzzle regarding the nature of his trip. If David is heading to war, his army is noticeably absent, and if he is traveling on an official mission for the king, his servants and attendants should be by his side [מלבי״ם].
