Revelation 14:6-8
6 And I saw another angel flying in midheaven, having an eternal gospel to preach to those who live on the earth, and to every nation and tribe and tongue and people; 7 and he said with a loud voice, “Fear God, and give Him glory, because the hour of His judgment has come; worship Him who made the heaven and the earth and sea and springs of waters.”
8 And another angel, a second one, followed, saying, “Fallen, fallen is Babylon the great, she who has made all the nations drink of the wine of the passion of her immorality.”
