Leviticus 20:5-8

⁵Then my face will be turned against him and his family, and he and all those who do evil with him will be cut off from among their people.

⁶And whoever goes after those who make use of spirits and wonder-workers, doing evil with them, against him will my face be turned, and he will be cut off from among his people.

⁷So make and keep yourselves holy, for I am the Lord your God.

⁸And keep my rules and do them: I am the Lord, who make you holy.
