Revelation 2:9-11 World English Bible (WEB)
9 “I know your works, oppression, and your poverty (but you are rich), and the blasphemy of those who say they are Jews, and they are not, but are a synagogue of Satan. 10 Don’t be afraid of the things which you are about to suffer. Behold, the devil is about to throw some of you into prison, that you may be tested; and you will have oppression for ten days. Be faithful to death, and I will give you the crown of life. 11 He who has an ear, let him hear what the Spirit says to the assemblies. He who overcomes won’t be harmed by the second death.
