5then I Myself will set My face against that man and against his family, and I will cut off from among their people both him and all those who play the prostitute with him, by playing the prostitute with Molech.

6‘As for the person who turns to 12mediums and to spiritists, to play the prostitute with them, I will also set My face against that person and will cut him off from among his people.
