Barnes' Notes
It is manifest both that the apparition of Samuel was real, and also that the woman was utterly unprepared for it.
Why hast thou deceived me ... - She perhaps inferred that Samuel would have answered the call of none inferior to the king. Or it may be the presence of an inhabitant of the world of spirits brought a sudden illumination to her mind.
