4 They fell down and worshiped the dragon because he gave his authority to the beast; they also worshiped the beast, saying, “Who is like (as great as) the beast, and who is able to wage war against him?” 5 And the beast was given a mouth (the power of speech), uttering great things and arrogant and blasphemous words, and he was given freedom and authority to act and to do as he pleased for (a)forty-two months (three and a half years).(A) 6 And he opened his mouth to speak blasphemies (abusive speech, slander) against God, to blaspheme His name and His tabernacle, and those who live in heaven.
7 He was also (b)permitted to wage war against the saints (God’s people) and to overcome them, and authority and power over every tribe and people and language and nation.(B) 8 All the inhabitants of the earth will fall down and worship him, everyone whose name has not been written since the foundation of the world in the Book of Life of the Lamb who has been slain [as a willing sacrifice]. 9 If anyone has an ear, let him hear. 10 If anyone is destined for captivity, he will go into captivity; if anyone kills with a sword, he must be killed with a sword. Here is [the call for] the patient endurance and the faithfulness of the saints [which is seen in the response of God’s people to difficult times].(C)
