Leviticus 20:23-27

Furthermore, you shall not follow the customs of the nation which I am going to drive out before you, because they did all these things; therefore I have felt disgust for them.

So I have said to you, “You are to take possession of their land, and I Myself will give it to you to possess, a land flowing with milk and honey.” I am the Lord your God, who has singled you out from the peoples.

You are therefore to make a distinction between the clean animal and the unclean, and between the unclean bird and the clean; and you shall not make yourselves detestable by animal or by bird, or by anything that crawls on the ground, which I have distinguished for you as unclean.

So you are to be holy to Me, for I the Lord am holy; and I have singled you out from the peoples to be Mine.

‘Now a man or a woman who is a medium or a spiritist must be put to death. They shall be stoned with stones; they have brought their own deaths upon themselves.’ ”
