2 Corinthians 11:3

11:3 But I am afraid that just as the serpent deceived Eve by his treachery, your minds may be led astray from a sincere and pure devotion to Christ.

Romans 16:18-19

16:18 For these are the kind who do not serve our Lord Christ, but their own appetites. By their smooth talk and flattery they deceive the minds of the naive. 16:19 Your obedience is known to all and thus I rejoice over you. But I want you to be wise in what is good and innocent in what is evil.
