Revelation 2:12-17

2:12 And to the angel of the church in Pergamos write; These things saith he which hath the sharp sword with two edges;

2:13 I know thy works, and where thou dwellest, [even] where  Satan's seat [is]: and thou holdest fast my name, and hast not denied my faith, even in those days wherein Antipas [was] my faithful martyr, who was slain among you, where Satan dwelleth.

2:14 But I have a few things against thee, because thou hast there them that hold the doctrine of Balaam, who taught Balac to cast a stumblingblock before the children of Israel, to eat things sacrificed unto idols, and to commit fornication.

2:15 So hast thou also them that hold the doctrine of the Nicolaitans, which thing I hate.

2:16 Repent; or else I will come unto thee quickly, and will fight against them with the sword of my mouth.

2:17 He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh 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 knoweth saving he that receiveth [it].
