Revelation 2:14-16 CSB
But I have a few things against you. You have some there who hold to the teaching of Balaam, who taught Balak to place a stumbling block in front of the Israelites: to eat meat sacrificed to idols and to commit sexual immorality. In the same way, you also have those who hold to the teaching of the Nicolaitans. So repent! Otherwise, I will come to you quickly and fight against them with the sword of my mouth.
