Leviticus 20:5-7

Amplified Bible

⁵ then I shall set My face against that man and against his [extended] family, and I will cut off from their people both him and all who follow him in ^[a]playing the prostitute (commit apostasy) with Molech.

⁶ ‘As for the person who turns to mediums [who consult the dead] or to spiritists, to play the prostitute after them, I shall set My face against that person and will cut him off from his people [excluding him from the atonement made for them].^{(A) 7} You shall consecrate yourselves therefore, and be holy; for I am the Lord your God.
