1 Samuel 28:1-7, 15-20

Now it came about in those days that the Philistines gathered their armed camps for war, to fight against Israel. And Achish said to David, “Know assuredly that you will go out with me in the camp, you and your men.” David said to Achish, “Very well, you shall know what your servant can do.” So Achish said to David, “Very well, I will make you my bodyguard for life.” Now Samuel was dead, and all Israel had lamented him and buried him in Ramah, his own city. And Saul had removed from the land those who were mediums and spiritists. So the Philistines gathered together and came and camped in Shunem; and Saul gathered all Israel together and they camped in Gilboa. When Saul saw the camp of the Philistines, he was afraid and his heart trembled greatly. 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 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 woman who is a medium at En-dor.”

Then Samuel said to Saul, “Why have you disturbed me by bringing me up?” And Saul answered, “I am greatly distressed; for the Philistines are waging war against me, and God has departed from me and no longer answers me, either through prophets or by dreams; therefore I have called you, that you may make known to me what I should do.” Samuel said, “Why then do you ask me, since the LORD has departed from you and has become your adversary? The LORD has done accordingly as He spoke through me; for the LORD has torn the kingdom out of your hand and given it to your neighbor, to David. As you did not obey the LORD and did not execute His fierce wrath on Amalek, so the LORD has done this thing to you this day. Moreover the LORD will also give over Israel along with you into the hands of the Philistines, therefore tomorrow you and your sons will be with me. Indeed the LORD will give over the army of Israel into the hands of the Philistines!” Then Saul immediately fell full length upon the ground and was very afraid because of the words of Samuel; also there was no strength in him, for he had eaten no food all day and all night.
