Revelation 2:6-7

2:6 But you do have this going for you: You hate what the Nicolaitans practice – practices I also hate. 2:7 The one who has an ear had better hear what the Spirit says to the churches. To the one who conquers, I will permit him to eat from the tree of life that is in the paradise of God.’

Revelation 2:15

2:15 In the same way, there are also some among you who follow the teaching of the Nicolaitans.
