Revelation 2:12-13

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.
