1 Samuel 28:10

6 He inquired of the LORD, but the LORD did not answer him by dreams or Urim or prophets.

7 Then Saul said to his servants, “Find me a woman who is a medium, so I can go and consult her.” “There is a medium at Endor,” his servants replied.

8 So Saul disguised himself by putting on different clothes, and he set out with two of his men. They came to the woman at night, and Saul said, “Consult a spirit for me. Bring up for me the one I name.”

9 But the woman replied, “Surely you know what Saul has done, how he has killed the mediums and spiritists in the land. Why have you set a trap to get me killed?”

10 Then Saul swore to her by the LORD: “As surely as the LORD lives, no punishment shall come upon you for this.”

11 “Whom shall I bring up for you?” the woman asked. “Bring up Samuel,” he replied.

12 But when the woman saw Samuel, she cried out in a loud voice and said to Saul, “Why have you deceived me? You are Saul!”

13 “Do not be afraid,” the king replied. “What do you see?” “I see a god coming up out of the earth,” the woman answered.

14 “What does he look like?” asked Saul. “An old man is coming up,” she replied. “And he is wearing a robe.” So Saul knew that it was Samuel, and he bowed facedown in reverence.
