1 Samuel 28:3, 7-9

Now Samuel was dead, and all the Israelites had shown their sadness for him. They had buried Samuel in his hometown of Ramah. And Saul had forced out the mediums and fortune-tellers from the land.

Then Saul said to his servants, “Find me a woman who is a medium so I may go and ask her what will happen.” His servants answered, “There is a medium in Endor.” Then Saul put on other clothes to disguise himself, and at night he and two of his men went to see the woman. Saul said to her, “Talk to a spirit for me. Bring up the person I name.” But the woman said to him, “Surely you know what Saul has done. He has forced the mediums and fortune-tellers from the land. You are trying to trap me and get me killed.”
