Revelation 2:13-15

Darby Translation

¹³ I know where thou dwellest, where the throne of Satan [is]; and thou holdest fast my name, and hast not denied my faith, even in the days in which Antipas my faithful witness [was], who was slain among you, where Satan dwells.

¹⁴ But I have a few things against thee: that thou hast there those who hold the doctrine of Balaam, who taught Balak to cast a snare before the sons of Israel, to eat [of] idol sacrifices and commit fornication.

¹⁵ So thou also hast those who hold the doctrine of Nicolaitanes in like manner.
