Isaiah

So Saul died for his transgression which he committed against the Lord, even against the word of the Lord, which he kept not, and also for asking counsel of one that had a familiar spirit, to enquire of it;

And the soul that turneth after such as have familiar spirits, and after wizards, to go a whoring after them, I will even set my face against that soul, and will cut him off from among his people.

And he caused his children to pass through the fire in the valley of the son of Hinnom: also he observed times, and used enchantments, and used witchcraft, and dealt with a familiar spirit, and with wizards: he wrought much evil in the sight of the Lord, to provoke him to anger.

Regard not them that have familiar spirits, neither seek after wizards, to be defiled by them: I am the Lord your God.

They joined themselves also unto Baal–peor, and ate the sacrifices of the dead.
