War against the Saints

Revelation 13:4-7
Men worshiped the dragon because he had given authority to the beast, and they also worshiped the beast and asked, "Who is like the beast? Who can make war against him?"

 The beast was given a mouth to utter proud words and blasphemies and to exercise his authority for forty-two months. He opened his mouth to blaspheme God, and to slander his name and his dwelling place and those who live in heaven. He was given power to make war against the saints and to conquer them. And he was given authority over every tribe, people, language and nation.
