1 Samuel 28:12-14

12 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!”

13 The king said to her, “Don’t be afraid. What do you see?”
The woman said, “I see a spirit coming up out of the ground.”

14 “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.
