1 Samuel 28:12 (KJV)

And Saul sware to her by the Lord, saying, As the Lord liveth, there shall no punishment happen to thee for this thing.

Then said the woman, Whom shall I bring up unto thee? And he said, Bring me up Samuel.

And when the woman saw Samuel, she cried with a loud voice: and the woman spake to Saul, saying, Why hast thou deceived me? for thou art Saul.

And the king said unto her, Be not afraid: for what sawest thou? And the woman said unto Saul, I saw gods ascending out of the earth.

And he said unto her, What form is he of? And she said, An old man cometh up; and he is covered with a mantle. And Saul perceived that it was Samuel, and he stooped with his face to the ground, and bowed himself.
