Bible, King James Version, Revelations 2.

Bible, King James Version: [12] And to the angel of the church in Pergamos write; These things saith he which hath the sharp sword with two edges; [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. [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.
