'Mediums' in the Bible

"So when they advise you, "Ask the mediums your questions, and quiz the spiritists who chirp and mutter,' shouldn't a people instead be consulting their God and not the dead on behalf of those who are living

They [who consult mediums and soothsayers] will pass through the land deeply distressed and hungry, and when they are hungry, they will become enraged and will curse their king and their God as they look upward.

The spirits of the Egyptians within them will be drained of courage, and I will bring their plans to nothing. They will consult idols and spirits of the dead, and mediums and spiritists.
