2:14 But I have a few things against you: You have some people there who follow the teaching of Balaam, who instructed Balak to put a stumbling block before the people of Israel so they would eat food sacrificed to idols and commit sexual immorality.

Revelation 2:20-21

2:20 But I have this against you: You tolerate that woman Jezebel, who calls herself a prophetess, and by her teaching deceives my servants to commit sexual immorality and to eat food sacrificed to idols. 2:21 I have given her time to repent, but she is not willing to repent of her sexual immorality.
