'Spirits' in the Bible

When they tell you, "Consult with those who have familiar spirits and with the wizards, who chirp and who mutter:" shouldn't a people consult with their God? Should they consult the dead on behalf of the living?

The spirit of Egypt will fail in its midst. I will destroy its counsel. They will seek the idols, the charmers, those who have familiar spirits, and the wizards.
