Revelation 2:9-10
To the Church in Smyrna.
I know your tribulation and your poverty (but you are rich) and the slander of those who say that they are Jews and are not, but are a synagogue of Satan. Do not fear what you are about to suffer.
Behold, the devil is about to throw some of you into prison, that you may be tested, and for ten days you will have tribulation.
Be faithful unto death, and I will give you the crown of life.
