Revelation 2:12-17

12And to the angel of the assembly in Pergamos write: These things says he that has the sharp two-edged sword:

13I know where thou dwellest, where the throne of Satan [is]; and thou holdest fast my name, and hast not denied my faith, even in the days in which Antipas my faithful witness [was], who was slain among you, where Satan dwells.

14But I have a few things against thee: that thou hast there those who hold the doctrine of Balaam, who taught Balak to cast a snare before the sons of Israel, to eat [of] idol sacrifices and commit fornication.

15So thou also hast those who hold the doctrine of Nicolaitanes in like manner.

16Repent therefore: but if not, I come to thee quickly, and I will make war with them with the sword of my mouth.

17He that has an ear, let him hear what the Spirit says to the assemblies. To him that overcomes, to him will I give of the hidden manna; and I will give to him a white stone, and on the stone a new name written, which no one knows but he that receives [it].
