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.

2 Corinthians 11:13-15

11:13 For such people are false apostles, deceitful workers, disguising themselves as apostles of Christ. 11:14 And no wonder, for even Satan disguises himself as an angel of light. 11:15 Therefore it is not surprising his servants also disguise themselves as servants of righteousness, whose end will correspond to their actions.
