Revelation 2:13-16

13I know thy works, and where thou dwellest, even where Satan’s throne is : and thou holdest fast my name, and hast not denied my faith, even in those days in which Antipas was my faithful martyr, who was slain among you, where Satan dwelleth. 14But I have a few things against thee, because thou hast there them that hold the doctrine of Balaam, who taught Balak to cast a stumblingblock before the children of Israel, to eat things sacrificed to idols, and to commit acts of immorality. 15So hast thou also them that hold the doctrine of the Nicolaitans, which thing I hate. 16Repent; or else I will come to thee quickly, and will fight against them with the sword of my mouth.
