Revelation 13:7-10
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!
13:10 If anyone is meant for captivity,
into captivity he will go.
If anyone is to be killed by the sword,
then by the sword he must be killed.
This requires steadfast endurance and faith from the saints.
Revelation 13:15-17
13:15 The second beast was empowered to give life to the image of the first beast so that it could speak, and could cause all those who did not worship the image of the beast to be killed.
13:16 He also caused everyone (small and great, rich and poor, free and slave) to obtain a mark on their right hand or on their forehead.
13:17 Thus no one was allowed to buy or sell things unless he bore the mark of the beast – that is, his name or his number.
