Leviticus 20:3-6

I will turn  against that man and cut him off from his people, because he gave his offspring to Molech, defiling my sanctuary  and profaning my holy name.  But if the people of the country look the other way when that man  gives any of his children to Molech, and do not put him to death, then I will turn against that man and his family, and cut off from their people both him and all who follow  him in prostituting  themselves with Molech. “Whoever turns to mediums  , or spiritists  and prostitutes himself with them, I will turn against that person and cut him off from his people.
