Revelation 2:14-16

Young's Literal Translation

¹⁴ `But I have against thee a few things: That thou hast there those holding the teaching of Balaam, who did teach Balak to cast a stumbling-block before the sons of Israel, to eat idol-sacrifices, and to commit whoredom;

¹⁵ so hast thou, even thou, those holding the teaching of the Nicolaitans -- which thing I hate.

¹⁶ `Reform! and if not, I come to thee quickly, and will fight against them with the sword of my mouth.
