13.10 Jr 15.2; 43.11.
Then I saw another beast, which came up out of the earth. It had two horns like a lamb's horns, and it spoke like a dragon.
It used the vast authority of the first beast in its presence. It forced the earth and all who live on it to worship the first beast, whose wound had healed.
This second beast performed great miracles; it made fire come down out of heaven to earth in the sight of everyone.
And it deceived all the people living on earth by means of the miracles which it was allowed to perform in the presence of the first beast. The beast told them to build an image in honor of the beast that had been wounded by the sword and yet lived.
The second beast was allowed to breathe life into the image of the first beast, so that the image could talk and put to death all those who would not worship it.
The beast forced all the people, small and great, rich and poor, slave and free, to have a mark placed on their right hands or on their foreheads.
No one could buy or sell without this mark, that is, the beast's name or the number that stands for the name.
This calls for wisdom. Whoever is intelligent can figure out the meaning of the number of the beast, because the number stands for the name of someone. Its number is 666.
