1 Samuel 21:1-2
21:1 (21:2) David went to Ahimelech the priest in Nob. Ahimelech was shaking with fear when he met David, and said to him, “Why are you by yourself with no one accompanying you?”
21:2 David replied to Ahimelech the priest, “The king instructed me to do something, but he said to me, ‘Don’t let anyone know the reason I am sending you or the instructions I have given you.’ I have told my soldiers to wait at a certain place.
