'Familiar Spirits' in the Bible

And when they shall say unto you, Seek unto them that have familiar spirits, and unto wizards that peep, and that mutter: should not a people seek unto their God? for the living to the dead?

And the spirit of Egypt shall fail in the midst thereof; and I will destroy the counsel thereof: and they shall seek to the idols, and to the charmers, and to them that have familiar spirits, and to the wizards.
