Revelation 2:9-13

9I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them who say they are Jews, and are not, but are the synagogue of Satan. 10Fear none of those things which thou shalt suffer: behold, the devil shall cast some of you into prison, that ye may be tried; and ye shall have tribulation ten days: be thou faithful to death, and I will give thee a crown of life. 11He that hath an ear, let him hear what the Spirit saith to the churches; He that overcometh shall not be hurt by the second death.

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