Revelation 2

14 But I have a few things against you: that you have there those holding the teaching of Balaam, who taught Balak to cast a stumbling-block before the sons of Israel, to eat idol-sacrifices, and to commit whoredom; 15 so have you, even you, those holding the teaching of the Nicolaitans—which thing I hate. 16 Convert! And if not, I come to you quickly, and will fight against them with the sword of My mouth.
