13:1 And I saw a beast rising out of the sea, with ten horns and seven heads, with ten diadems on its horns and blasphemous names on its heads. 2 And the beast that I saw was like a leopard; its feet were like a bear's, and its mouth was like a lion's mouth. And to it the dragon gave his power and his throne and great authority. 3 One of its heads seemed to have a mortal wound, but its mortal wound was healed, and the whole earth marveled as they followed the beast. 4 And they 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 language and nation, 8 and all who dwell on earth will worship it, everyone whose name has not been written before the foundation of the world in the book of life of the Lamb who was slain. 9 If anyone has an ear, let him hear:

Here is a call for the endurance and faith of the saints. (ESV)
