Says a lot about the old woman. She was asked to conjur up Samuel and is shocked when Samuel actually appears. Could be that she wasn't expecting Samuel as she normally didn't really conjur up spirits but illusions of her own making. (Trickery)1Sa 28:11 Then said the woman, Whom shall I bring up unto thee? And he said, Bring me up Samuel.
12 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.
13 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.
14 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.
