Rev 13
5 The beast was given a mouth to utter proud words and blasphemies and to exercise its authority for forty-two months. 6 It opened its mouth to blaspheme God, and to slander his name and his dwelling place and those who live in heaven. 7 It was given power to wage war against God’s holy people and to conquer them. And it was given authority over every tribe, people, language and nation. 8 All inhabitants of the earth will worship the beast—all whose names have not been written in the Lamb’s book of life, the Lamb who was slain from the creation of the world.
11 Then I saw a second beast, coming out of the earth. It had two horns like a lamb, but it spoke like a dragon. 12 It exercised all the authority of the first beast on its behalf, and made the earth and its inhabitants worship the first beast, whose fatal wound had been healed.
The second beast was given power to give breath to the image of the first beast, so that the image could speak and cause all who refused to worship the image to be killed. 16 It also forced all people, great and small, rich and poor, free and slave, to receive a mark on their right hands or on their foreheads, 17 so that they could not buy or sell unless they had the mark, which is the name of the beast or the number of its name.
18 This calls for wisdom. Let the person who has insight calculate the number of the beast, for it is the number of a man. That number is 666.
So we have one beast in verse 5 that had authority for 42 months. Who is that? And what is the "Lamb's book of life"?
In verse 11 there is a second beast and this one is associated with the "number of a man...666" And Baha'is say this beast is not a man but the year 666? Please explain. Thanks.
