1st Samuel 28:5

2 And David said to Achish, You will see now what your servant will do. And Achish said to David, Then I will make you keeper of my head for ever.

3 Now Samuel was dead, and all Israel, after weeping for him, had put his body in its last resting-place in Ramah, his town. And Saul had put away from the land all those who had control of spirits and who made use of secret arts.

4 And the Philistines came together and put their forces in position in Shunem; and Saul got all Israel together and they took up their positions in Gilboa.

5 And when Saul saw the Philistine army he was troubled, and his heart was moved with fear.

6 And when Saul went for directions to the Lord, the Lord gave him no answer, by a dream or by the Urim or by the prophets.

7 Then Saul said to his servants, Get me a woman who has control of a spirit so that I may go to her and get directions. And his servants said to him, There is such a woman at En-dor.

8 So Saul, putting on other clothing, so that he might not be seen to be the king, took two men with him and went to the woman by night; and he said, Now, with the help of the spirit which you have, make the person whose name I will give you come up.
