Revelation 13:11-18 - The Second Beast From The Earth

¹¹ Then I saw another beast coming up from the earth. He had two horns like a lamb, but was speaking like a dragon. ¹² He exercised all the ruling authority of the first beast on his behalf, and made the earth and those who inhabit it worship the first beast, the one whose lethal wound had been healed. ¹³ He performed momentous signs, even making fire come down from heaven in front of people ¹⁴ and, by the signs he was permitted to perform on behalf of the beast, he deceived those who live on the earth. He told those who live on the earth to make an image to the beast who had been wounded by the sword, but still lived. 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. 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. 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.

¹⁸ This calls for wisdom: Let the one who has insight calculate the beast's number, for it is man's number, and his number is 666.
