Acts 20:29-31

29 I know that after my departure fierce wolves will come in among you, not sparing the flock;

30 and from among your own selves will arise men speaking twisted things, to draw away the disciples after them.

31 Therefore be alert, remembering that for three years I did not cease night or day to admonish everyone with tears.

2 Corinthians 11:13-15

13 For such men are false apostles, deceitful workmen, disguising themselves as apostles of Christ.

14 And no wonder, for even Satan disguises himself as an angel of light.

15 So it is no surprise if his servants, also, disguise themselves as servants of righteousness. Their end will correspond to their deeds.

1 Timothy 4:1-3

1 Now the Spirit expressly says that in later times some will depart from the faith by devoting themselves to deceitful spirits and teachings of demons,

2 through the insincerity of liars whose consciences are seared,

3 who forbid marriage and require abstinence from foods that God created to be received with thanksgiving by those who believe and know the truth.

2 Peter 2:1

1 But false prophets also arose among the people, just as there will be false teachers among you, who will secretly bring in destructive heresies, even denying the Master who bought them, bringing upon themselves swift destruction.

1 John 2:26

26 I write these things to you about those who are trying to deceive you.
