2 Cor. 11:13-14
For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ.  And no marvel; for Satan himself is transformed into an angel of light.
I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel:  Which is not another [of same kind, that is]; but there be some that trouble you,

There shall not be found among you any one that maketh his son or his daughter to pass through the fire, or that useth divination, or an observer of times, or an enchanter, or a witch,  Or
a charmer, or a consulter with familiar spirits, or a wizard, or a necromancer.  For all that do these things are an abomination unto the Lord: and because of these abominations the Lord thy God doth drive them out from before thee.
1 John 4:1
Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
Thou believest that there is one God; thou doest well: the devils also believe, and tremble.
And unclean spirits, when they saw him, fell down before him, and cried, saying, Thou art the Son of God.
And, behold, they cried out, saying, What have we to do with thee, Jesus, thou Son of God? art thou come hither to torment us before the time?
