Revelation 2:13-15

Young's Literal Translation

¹³ I have known thy works, and where thou dost dwell -- where the throne of the Adversary [is] -- and thou dost hold fast my name, and thou didst not deny my faith, even in the days in which Antipas [was] my faithful witness, who was put to death beside you, where the Adversary doth dwell.

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.
