Revelation 2:12-13

12And to the angel of the church in Pergamum write:

These things saith he that hath the sharp two-edged sword: 13I know where thou dwellest, even where Satan’s throne is; and thou holdest fast my name, and didst not deny my faith, even in the days of Antipas my witness, my faithful one, who was killed among you, where Satan dwelleth.
