Revelation 2:14-16

14But I have a few things against thee, because thou hast there them that hold the doctrine of Balaam, who taught Balak to cast a stumblingblock before the children of Israel, to eat things sacrificed to idols, and to commit acts of immorality. 15So hast thou also them that hold the doctrine of the Nicolaitans, which thing I hate. 16Repent; or else I will come to thee quickly, and will fight against them with the sword of my mouth.
