Another beast appeared, having the same authority to rule people that the first beast had, and it caused people on earth to worship the first beast. People made an image of the first beast, and the beast had everyone killed who refused to worship the image. It caused all people to be marked with the name of the first beast. The number of the beast’s name is 666.

Revelation 13:11-18

11 I saw another beast, which was coming up from the earth. It had two small horns on its head like a sheep has. But it spoke things to deceive people, like the dragon does. 12 While the first beast watched, it used all the same authority to rule people that the first beast had. It forced the people who live on the earth [MTY, DOU] to worship the first beast, that is, the one who was healed of the wound that had caused it to almost die. 13 The second beast performed awesome miracles, even causing fire from the sky to fall to earth while people watched. 14 He performed miracles ◄on behalf of/with the authority of► the first beast. By doing that he deceived the unbelieving people on the earth so that they believed that they should worship the first beast. But this happened only because God allowed it to happen. The second beast told the people living on earth to make an image of the first beast, the one that people had almost killed with a sword and that then came back to life again. 15 The image of the first beast was allowed to breathe, in order that it might speak and in order that it might command that whoever refused to worship its image should be killed {that people should kill whoever refused to worship its image}. 16 The second beast required also that the first beast’s name be marked {its agents mark the first beast’s name} on the right hand or on the forehead of everyone, those of little social importance and of great social importance, the rich and the poor, free people and slaves. Everyone! 17 They did this in order that people could not buy anything or sell anything if they did not have the mark, which represents the name of the beast or the number of its name, on their foreheads. 18 You must think wisely to understand the meaning of the mark. Anyone who thinks wisely should calculate from the number of the beast what the man’s name is. That number is 666.
