Then came David to Nob to Ahimelech the priest: and Ahimelech was afraid at the meeting of David, and said unto him, Why art thou alone, and no man with thee? Then came David to Nob - There were two places of this name, one on this side, the second on the other side of Jordan; but it is generally supposed that Nob, near Gibeah of Benjamin, is the place here intended; it was about twelve miles from Jerusalem.
Why art thou alone - Ahimelech probably knew nothing of the difference between Saul and David; and as he knew him to be the king's son-in-law, he wondered to see him come without any attendants.
