Revelation 2:14-17

But I have a few things against you, because you have there those who hold the doctrine of Balaam, who taught Balak to put a stumbling block before the children of Israel, to eat things sacrificed to idols, and to commit sexual immorality. Thus you also have those who hold the doctrine of the Nicolaitans, which thing I hate. Repent, or else I will come to you quickly and will fight against them with the sword of My mouth. “He who has an ear, let him hear what the Spirit says to the churches. To him who overcomes I will give some of the hidden manna to eat. And I will give him a white stone, and on the stone a new name written which no one knows except him who receives it.” ’
