Revelation 2:10-15

10Do not be afraid of what you are about to suffer. I tell you, the devil will put some of you in prison to test you, and you will suffer persecution for ten days. Be faithful, even to the point of death, and I will give you life as your victor’s crown.

11Whoever has ears, let them hear what the Spirit says to the churches. The one who is victorious will not be hurt at all by the second death.

To the Church in Pergamum 12“To the angel of the church in Pergamum write: These are the words of him who has the sharp, double-edged sword.

13I know where you live—where Satan has his throne. Yet you remain true to my name. You did not renounce your faith in me, not even in the days of Antipas, my faithful witness, who was put to death in your city—where Satan lives. 14Nevertheless, I have a few things against you: There are some among you who hold to the teaching of Balaam, who taught Balak to entice the Israelites to sin so that they ate food sacrificed to idols and committed sexual immorality. 15Likewise, you also have those who hold to the teaching of the Nicolaitans.
