Revelation 2

14 But I have against thee a few things: 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, and to commit fornication: 15 So hast thou also them that hold the doctrine of the Nicolaites. 16 In like manner do penance: if not, I will come to thee quickly, and will fight against them with the sword of my mouth.
