Revelation 2:8-11 CSB
“Write to the angel of the church in Smyrna: Thus says the First and the Last, the one who was dead and came to life: I know your affliction and poverty, but you are rich. I know the slander of those who say they are Jews and are not, but are a synagogue of Satan. Don’t be afraid of what you are about to suffer. Look, the devil is about to throw some of you into prison to test you, and you will experience affliction for ten days. Be faithful to the point of death, and I will give you the crown of life.
“Let anyone who has ears to hear listen to what the Spirit says to the churches. The one who conquers will never be harmed by the second death.
