Revelation 2:9-10

9 'I know your 1tribulation and your 2poverty (but you are 3rich ), and the blasphemy by those who 4say they are Jews and are not, but are a synagogue of 5Satan.
10 'Do not fear what you are about to suffer. Behold, the devil is about to cast some of you into prison, so that you will be 6tested, and you will have tribulation 7for ten days. Be 8faithful until death, and I will give you 9the crown of life.
