David decides to cut a deal with the Philistines. In return for protection from Saul, he will join them in attacking his fellow Israelites. He has, in fact, no real intention of doing any such thing. Meanwhile, Saul is barely holding out against the Philistines and desperate oy turns to the Witch of Endor for guidance. The ghost of Samuel appears, but he refuses to help Saul and tells him he'll be dead by the next day. This comes to pass when Saul is finally defeated by a strong Philistine force and is killed, along with his son Jonathan. (1 Samuel 28:3-5)
