Ezekiel 14:7-8

7For anyone of the house of Israel, or of the strangers who dwell in Israel, who separates himself from Me and sets up his idols in his heart and puts before him what causes him to stumble into iniquity, then comes to a prophet to inquire of him concerning Me, I the Lord will answer him by Myself.

8I will set My face against that man and make him a sign and a proverb, and I will cut him off from the midst of My people. Then you shall know that I am the Lord.
