Revelation 2:14
"But I have a few things against you because you have people there [in the church] who hold to the teaching of Balaam, who taught Balak to place a stumblingblock in front of the Israelites, [causing them] to eat food sacrificed to idols and to be sexually immoral [See Num. 23-24].
Revelation 2:20
But I have this against you, that you tolerate that woman [named] Jezebel, who calls herself a prophetess. She teaches and deceives my servants into [practicing] sexual immorality and into eating things sacrificed to idols.
Revelation 18:1-5
After these things I saw another angel coming down from heaven. He had great authority, and the earth was illuminated by his splendor.
