Christ exhorts the congregation at Pergamum to stop listening to what the Nicolaitans teach.

Revelation 2:12-17

12 “Write this message to the leader [MET] of the congregation in Pergamum city: ‘I am saying these things to you. I am the one who has the sharp two-edged sword. 13 I know where you live: It is where Satan controls [MTY] people. I know that you firmly believe in me [MTY]. You did not deny that you believe/trust in me, not even in the time when Antipas, ◄my faithful witness/who faithfully told people about me►, was alive. He was killed {People killed him} in your city, a city where people habitually obey Satan. 14 Nevertheless, I have this complaint against you: You permit some of your members to teach things like Balaam taught long ago. He taught Balak to persuade the Israeli people to sin. Specifically, he taught them to eat food that had been offered to idols, and to practice sexual immorality. 15 In that way, you are also permitting some of your members to practice what the Nicolaitans teach, which is like what Balaam taught. 16 So you must stop doing this. If you do not stop doing it, I will come to you suddenly. Using the words that I will say I will fight against those who believe this false teaching [MTY], and I will ◄condemn them/say that they must be punished►. 17 Everyone who wants to understand [MTY] must listen carefully to the message that God’s Spirit speaks to the congregations. To everyone who conquers Satan, I will give blessings that will be like the food called manna that is in a jar that is {that someone has} hidden. I will also give them a white stone on which I will engrave a new name, a name that no one but the ones who receive it will know.’ ”
