Forced into Hiding, I Samuel 23-24, OT S1:E169

David, even while hiding from Saul, rises to rescue the town of Keilah. Betrayed by those he rescued, he retreats to En Gedi, where he gets a chance to take the life or his arch-enemy Saul. Instead, he shows Saul mercy, buying a slight reprieve by a ninja-like act of bravery.
