1 Samuel 28:7-8

7So Saul said to his servants, ‘Look for a woman who can talk to dead people. Then I will go and ask her what will happen.’ His servants replied, ‘There is a woman at Endor who can do that.’

8Saul changed his clothes so that no one would recognize him. At night, Saul and two of his men went to see the woman. Saul said to her, ‘Use your magic to bring up the spirit of a certain dead man. I will tell you his name.’
