Revelation 2,6: You hate the works of the Nicolaitans, what they are doing as corrupters of the people, which I Myself also detest.
Revelation 2,14: Nevertheless, I have a few things against you: you have some people there who are clinging to the teaching of Balaam, who taught Balak to set a trap and a stumbling block before the sons of Israel, to entice them to eat food that had been sacrificed to idols and to practice whoring. You also have some who in a similar way are clinging to the teaching of the Nicolaitans which thing I hate.
