1 In those days the Philistines gathered their forces to fight against Israel. Achish said to David, “You must understand that you and your men will accompany me in the army.”
2 David said, “Then you will see for yourself what your servant can do.” Achish replied, “Very well, I will make you my bodyguard for life.”

Saul and the Medium at Endor

3 Now Samuel was dead, and all Israel had mourned for him and buried him in his own town of Ramah. Saul had expelled the mediums and spiritists from the land.
4 The Philistines assembled and came and set up camp at Shunem, while Saul gathered all Israel and set up camp at Gilboa.
5 When Saul saw the Philistine army, he was afraid; terror filled his heart.
6 He inquired of the LORD, but the LORD did not answer him by dreams or Urim or prophets.
