Leviticus 20:4-6

Amplified Bible

⁴ If the people of the land should ever tolerate that man when he gives any of his children [as a burnt offering] to Molech, and fail to put him to death [as My law requires], 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)
