Revelation 2:14-15; Revelation 2:20

14 “But I have a few complaints against you. You tolerate some among you whose teaching is like that of Balaam, who showed Balak how to trip up the people of Israel. He taught them to sin by eating food offered to idols and by committing sexual sin. 15 In a similar way, you have some Nicolaitans among you who follow the same teaching.
20 “But I have this complaint against you. You are permitting that woman—that Jezebel who calls herself a prophet—to lead my servants astray. She teaches them to commit sexual sin and to eat food offered to idols.
