Revelation 2:8-11 - The Letter To The Church In Smyrna
8 And to the angel of the church of Smyrna write, These things saith the First and the Last, who was dead and is alive. 9 I know thy affliction and poverty, (but thou art rich) and the reviling of those who say they are Jews and are not, but a synagogue of Satan. 10 Fear none of those things which thou art about to suffer: behold the devil is about to cast some of you into prison that ye may be tried, and ye shall have affliction ten days: Be thou faithful unto death, and I will give thee the crown of life.
11 He that hath an ear, let him hear what the Spirit saith to the churches: He that overcometh shall not be hurt by the second death.
