David at Nob & Gath

As David flees Saul, he goes to Nob where he tells Ahimelech the Priest that he is on a special mission from the king. The priest feeds David and his men consecrated bread, thus sustaining their life. Was this acceptable? Was David being dishonest with the priest? These and other questions are addressed. This message also deals with David's time in Gath when he feigned insanity to save his life.
