Revelation 2:12-15

“Write this to the angel of the church in Pergamum: These are the words of the one who has the sharp, two-edged sword: I know that you are living right where Satan’s throne is. You are holding on to my name, and you didn’t break faith with me even at the time that Antipas, my faithful witness, was killed among you, where Satan lives. But I have a few things against you, because you have some there who follow Balaam’s teaching. Balaam had taught Balak to trip up the Israelites so that they would eat food sacrificed to idols and commit sexual immorality. In the same way, you have some who follow the Nicolaitans’ teaching.
