Revelation 2:12-17 - The Letter To The Church In Pergamum
12 And to the angel of the church in Pergamos, write: These things says he that has the sharp, two-edged sword; 13 I know your works, and where you dwell, even where the throne of Satan is: and yet you hold fast my name, and have not denied my faith, even in those days in which Antipas was my faithful witness, who was slain among you, where Satan dwells. 14 Yet I have a few things against you, that you have there those who hold the teaching of Balaam, who taught Balak to put a stumbling-block before the sons of Israel, to eat things sacrificed to idols, and to practice lewdness. 15 So, also, you have those who hold the teaching of the Nicolaitanes. 16 Repent, therefore; if not, I will come to you quickly, and I will fight against them with the sword of my mouth.
17 He that has an ear, let him hear what the Spirit says to the churches. To him that overcomes, I will give of the hidden manna; and I will give him a white stone, and on the stone a new name written, which no one knows but he that receives it.
