Revelation 2:9-11

Young's Literal Translation

⁹ I have known thy works, and tribulation, and poverty -- yet thou art rich -- and the evil-speaking of those saying themselves to be Jews, and are not, but [are] a synagogue of the Adversary.

¹⁰ `Be not afraid of the things that thou art about to suffer; lo, the devil is about to cast of you to prison, that ye may be tried, and ye shall have tribulation ten days; become thou faithful unto death, and I will give to thee the crown of the life.

¹¹ He who is having an ear -- let him hear what the Spirit saith to the assemblies: He who is overcoming may not be injured of the second death.
