And to the angel of the church in Pergamum write; These things says he who has the sharp sword with two edges; I know your works and where you dwell, even where Satan's throne is: and you hold fast my name, and have not denied my faith, even in those days when Antipas was my faithful martyr, who was slain among you, where Satan dwells.

But I have a few things against you, because you have there them that hold the doctrine of Balaam, who taught Balak to cast a stumbling block before the children of Israel, to eat things sacrificed unto idols, and to commit fornication. So have you also them that hold the doctrine of the Nicolaitans, which thing I hate. Repent; or else I will come unto you quickly, and will fight against them with the sword of my mouth. He that has an ear, let him hear what the Spirit says unto the churches; To him that overcomes will I give to eat of the hidden manna, and will give him a white stone, and in the stone a new name written, which no man knows except him who receives it. (Revelation 2:12-17)
