8 And vnto the Angel of the Church in Smyrna, write, These things saith the first and the last, which was dead, and is aliue,
9 I know thy works, and tribulation, and pouertie, but thou art rich, and I know the blasphemie of them which say they are Iewes and are not, but are the Synagogue of Satan.
10 Feare none of those things which thou shalt suffer: behold, the deuill shal cast some of you into prison, that ye may be tried, and yee shall haue tribulation tenne dayes: bee thou faithfull vnto death, and I will giue thee a crowne of life.
11 He that hath an eare, let him heare what the spirit saith vnto the churches. He that ouercommeth, shall not be hurt of the second death.
Rev 2:8-11
