Revelation 2:14-16, 20

Nevertheless, I have a few things against you. There are some among you who hold to the teachings of Balaam, who taught Balak to entice the Israelites to eat things that were sacrificed to idols and to commit sexual immorality. Furthermore, you have some who hold to the doctrines of the Nicolaitans. So repent, then, or I will come quickly to war against them with the sword of my mouth.

But I have this against you: you are forgiving that woman Jezebel, who calls herself a prophetess and is seducing my loving servants. She is teaching that it is permissible to indulge in sexual immorality and to eat food sacrificed to idols.
