Revelation 2:9, 13, 24

‘I know your tribulation and your poverty (but you are rich), and the blasphemy by those who say they are Jews and are not, but are a synagogue of Satan.

‘I know where you dwell, where Satan’s throne is; and you hold fast 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.

But I say to you, the rest who are in Thyatira, who do not hold this teaching, who have not known the deep things of Satan, as they call them—I place no other burden on you.
