Revelation 2:12
And to the angel of the church in Pergamos write; These things saith he which hath the sharp sword with two edges;
More from Revelation 2
Unto the angel of the church of Ephesus write; These things saith he that holdeth the seven stars in his right hand, who walketh in the midst of the seven golden candlesticks;
I know thy works, and thy labour, and thy patience, and how thou canst not bear them which are evil: and thou hast tried them which say they are apostles, and are not, and hast found them liars:
And hast borne, and hast patience, and for my name’s sake hast laboured, and hast not fainted.
Nevertheless I have somewhat against thee, because thou hast left thy first love.
Remember therefore from whence thou art fallen, and repent, and do the first works; or else I will come unto thee quickly, and will remove thy candlestick out of his place, except thou repent.
