1 Samuel 28:1-7, 15-20

In those days the Philistines gathered their forces for war, to fight against Israel. And Achish said to David, “Understand that you and your men are to go out with me in the army.” David said to Achish, “Very well, you shall know what your servant can do.” And Achish said to David, “Very well, I will make you my bodyguard for life.” Now Samuel had died, and all Israel had mourned for him and buried him in Ramah, his own city. And Saul had put the mediums and the necromancers out of the land. The Philistines assembled and came and encamped at Shunem. And Saul gathered all Israel, and they encamped at Gilboa. When Saul saw the army of the Philistines, he was afraid, and his heart trembled greatly. And when Saul inquired of the LORD, the LORD did not answer him, either by dreams, or by Urim, or by prophets. Then Saul said to his servants, “Seek out for me a woman who is a medium, that I may go to her and inquire of her.” And his servants said to him, “Behold, there is a medium at En-dor.”

Then Samuel said to Saul, “Why have you disturbed me by bringing me up?” Saul answered, “I am in great distress, for the Philistines are warring against me, and God has turned away from me and answers me no more, either by prophets or by dreams. Therefore I have summoned you to tell me what I shall do.” And Samuel said, “Why then do you ask me, since the LORD has turned from you and become your enemy? The LORD has done to you as he spoke by me, for the LORD has torn the kingdom out of your hand and given it to your neighbor, David. Because you did not obey the voice of the LORD and did not carry out his fierce wrath against Amalek, therefore the LORD has done this thing to you this day. Moreover, the LORD will give Israel also with you into the hand of the Philistines, and tomorrow you and your sons shall be with me. The LORD will give the army of Israel also into the hand of the Philistines.” Then Saul fell at once full length on the ground, filled with fear because of the words of Samuel. And there was no strength in him, for he had eaten nothing all day and all night.
