1 Samuel 21:1-2

1David went to the priest Ahimelech at Nob. Ahimelech was trembling as he went to meet David. “Why are you alone?” he asked David. “Why is no one with you?”

2“The king ordered me to do something,” David answered the priest Ahimelech, “and he told me, ‘No one must know anything about this mission I’m sending you on and about the orders I’ve given you. I’ve stationed  my young men at a certain place.’ ”
