Revelation 2:14-16

But I have a few things against thee, because thou hast there them that hold the doctrine of Balaam, who taught Balac to cast a stumblingblock before the children of Israel, to eat things sacrificed unto idols, and to commit fornication. So hast thou also them that hold the doctrine of the Nicolaitanes, which thing I hate. Repent; or else I will come unto thee quickly, and will fight against them with the sword of my mouth.
