Rev Revelation, chapter Revelation of Jesus Christ, chapter 13
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
The second beast performed awesome miracles, even causing fire from the sky to fall to earth while people watched.
