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 when they say to you, "Inquire of the mediums and the necromancers who chirp and mutter," should not a people inquire of their God? Should they inquire of the dead on behalf of the living?
Someone may say to you, “Let’s ask the mediums and those who consult the spirits of the dead. With their whisperings and mutterings, they will tell us what to do.” But shouldn’t people ask God for guidance? Should the living seek guidance from the dead?
