Revelation 2:9-11 Darby Translation (DARBY)
9 I know thy tribulation and thy poverty; but thou art rich; and the railing of those who say that they themselves are Jews, and are not, but a synagogue of Satan.
10 Fear nothing [of] what thou art about to suffer. Behold, the devil is about to cast 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 to thee the crown of life.
11 He that has an ear, let him hear what the Spirit says to the assemblies. He that overcomes shall in no wise be injured of the second death.
