Revelation 13:3-9

13:3 One of the beast’s heads appeared to have been killed, but the lethal wound had been healed. And the whole world followed the beast in amazement; 13:4 they worshiped the dragon because he had given ruling authority to the beast, and they worshiped the beast too, saying: “Who is like the beast?” and “Who is able to make war against him?” 13:5 The beast was given a mouth speaking proud words and blasphemies, and he was permitted to exercise ruling authority for forty-two months. 13:6 So the beast opened his mouth to blaspheme against God – to blaspheme both his name and his dwelling place, that is, those who dwell in heaven. 13:7 The beast was permitted to go to war against the saints and conquer them. He was given ruling authority over every tribe, people, language, and nation, 13:8 and all those who live on the earth will worship the beast, everyone whose name has not been written since the foundation of the world in the book of life belonging to the Lamb who was killed. 13:9 If anyone has an ear, he had better listen!

Revelation 17:12-13

17:12 The ten horns that you saw are ten kings who have not yet received a kingdom, but will receive ruling authority as kings with the beast for one hour. 17:13 These kings have a single intent, and they will give their power and authority to the beast.

Revelation 17:17

17:17 For God has put into their minds to carry out his purpose by making a decision to give their royal power to the beast until the words of God are fulfilled.
