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 last, who was dead, and is alive." 9 "I know thy works, thy tribulation and poverty (tho' thou art rich) and I know the blasphemy of those who say they are Jews, and are not, but are the synagogue of satan. 10 fear none of those things which thou shalt suffer: behold, the devil shall cast some of you into prison, that ye may be tried; and ye shall have tribulation ten days: be thou faithful unto death, and I will give thee a 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."
