Revelation 2:9-13

⁹‘I know your tribulation and your poverty (but you are rich), and the slander by those who say they are Jews, and are not, but are a synagogue of Satan. ¹⁰Do not fear what you are about to suffer. Behold, the devil is about to throw some of you into prison, so that you will be tested, and you will have tribulation for ten days. Be faithful until death, and I will give you the crown of life. ¹¹The one who has an ear, let him hear what the Spirit says to the churches. The one who overcomes will not be hurt by the second death.’

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

The One who has the sharp two-edged sword says this:

¹³‘I know where you dwell, where Satan’s throne is; and you hold firmly to My name, and did not deny My faith even in the days of Antipas, My witness, My faithful one, who was killed among you, where Satan dwells.
