Revelation 2:8-10

8“And to the angel of the church in Smyrna write, ‘These things says the First and the Last, who was dead, and came to life:

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

10Do not fear any of those things which you are about to suffer. Indeed, the devil is about to throw some of you into prison, that you may be tested, and you will have tribulation ten days. Be faithful until death, and I will give you the crown of life.
