Revelation 2:8-11

2:8 And unto the angel of the church in Smyrna write; These things saith the first and the last, which was dead, and is alive;

2:9 I know thy works, and tribulation, and poverty, (but thou art rich) and [I know] the blasphemy of them which say they are Jews, and are not, but [are] the synagogue of Satan.

2:10 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.

2:11 He that hath an ear, let him hear what the Spirit saith unto the churches; He that overcometh shall not be hurt of the second death.
