Revelation 2:14-16

14But I have a few things to say against you. Some people among you agree with what Balaam taught long ago. He taught Balak to do a bad thing against God's people. Balak caused the Israelite people to do wrong things. As a result, they ate food that people had given to idols. They also had sex with people who were not their husbands or wives.

15Also, some people among you do the bad things that the Nicolaitans teach.

16So you must stop doing these bad things. If you do not change how you live, I will quickly come to punish you. I will fight against those bad people with my sharp sword that comes out of my mouth.
