Leviticus 20:3-6

I myself will turn against them and cut them off from the community, because they have defiled my sanctuary and brought shame on my holy name by offering their children to Molech. And if the people of the community ignore those who offer their children to Molech and refuse to execute them, I myself will turn against them and their families and will cut them off from the community. This will happen to all who commit spiritual prostitution by worshiping Molech. “I will also turn against those who commit spiritual prostitution by putting their trust in mediums or in those who consult the spirits of the dead. I will cut them off from the community.
