Charles Ellicott Commentary 1 Samuel 28:23

"But he refused, and said, I will not eat. But his servants, together with the woman, constrained him; and he hearkened unto their voice. So he arose from the earth, and sat upon the bed." — 1 Samuel 28:23 (ASV)

And sat upon the bed —That is, upon the divan, or cushioned seat, which usually runs around the walls of rooms in Eastern dwellings. There is nothing in the narration to support the common idea, represented so often in painting, that the scene described above took place in a cave. The witch probably lived in a dwelling of her own at En-dor. There is also nothing in the narrative to indicate that she was living in a place of concealment.
