Revelation 13:6 In-Context

4 Men worshiped the dragon, for he had given his authority to the beast, and they worshiped the beast, saying, "Who is like the beast, and who can fight against it?"
5 And the beast was given a mouth uttering haughty and blasphemous words, and it was allowed to exercise authority for forty-two months;
6 it opened its mouth to utter blasphemies against God, blaspheming his name and his dwelling, that is, those who dwell in heaven.
7 Also it was allowed to make war on the saints and to conquer them. And authority was given it over every tribe and people and tongue and nation,
8 and all who dwell on earth will worship it, every one whose name has not been written before the foundation of the world in the book of life of the Lamb that was slain.
