1 Samuel 28:6-14

He enquired of the LORD, but the LORD did not answer him by dreams or Urim or prophets. Saul then said to his attendants, ‘Find me a woman who is a medium, so that I may go and enquire of her.’ ‘There is one in Endor,’ they said. So Saul disguised himself, putting on other clothes, and at night he and two men went to the woman. ‘Consult a spirit for me,’ he said, ‘and bring up for me the one I name.’ But the woman said to him, ‘Surely you know what Saul has done. He has cut off the mediums and spiritists from the land. Why have you set a trap for my life to bring about my death?’ Saul swore to her by the LORD, ‘As surely as the LORD lives, you will not be punished for this.’ Then the woman asked, ‘Whom shall I bring up for you?’ ‘Bring up Samuel,’ he said. When the woman saw Samuel, she cried out at the top of her voice and said to Saul, ‘Why have you deceived me? You are Saul!’ The king said to her, ‘Don’t be afraid. What do you see?’ The woman said, ‘I see a ghostly figure coming up out of the earth.’ ‘What does he look like?’ he asked. ‘An old man wearing a robe is coming up,’ she said. Then Saul knew it was Samuel, and he bowed down and prostrated himself with his face to the ground.
