Revelation 2

14 But I have a few things against you, because you have there those who hold the doctrine of *Num. 31:16Balaam, who taught Balak to put a stumbling block before the children of Israel, *Num. 25; Acts 15:29; (1 Cor. 10:20); Rev. 2:20to eat things sacrificed to idols, *1 Cor. 6:13and to commit sexual immorality.15 Thus you also have those who hold the doctrine of the Nicolaitans, which thing I hate.16 Repent, or else I will come to you quickly and *Is. 11:4; 2 Thess. 2:8; Rev. 19:15will fight against them with the sword of My mouth.
