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