Revelation 13:11-18 English Standard Version (ESV)
The Second Beast
11 Then I saw another beast rising out of the earth. It had two horns like a lamb and it spoke like a dragon. 12 It exercises all the authority of the first beast in its presence,[a] and makes the earth and its inhabitants worship the first beast, whose mortal wound was healed. 13 It performs great signs, even making fire come down from heaven to earth in front of people, 14 and by the signs that it is allowed to work in the presence of[b] the beast it deceives those who dwell on earth, telling them to make an image for the beast that was wounded by the sword and yet lived. 15 And it was allowed to give breath to the image of the beast, so that the image of the beast might even speak and might cause those who would not worship the image of the beast to be slain. 16 Also it causes all, both small and great, both rich and poor, both free and slave,[c] to be marked on the right hand or the forehead, 17 so that no one can buy or sell unless he has the mark, that is, the name of the beast or the number of its name. 18 This calls for wisdom: let the one who has understanding calculate the number of the beast, for it is the number of a man, and his number is 666.[d]
Revelation 13:11-18 New International Version (NIV)
The Beast out of the Earth
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. 13 And it performed great signs, even causing fire to come down from heaven to the earth in full view of the people. 14 Because of the signs it was given power to perform on behalf of the first beast, it deceived the inhabitants of the earth. It ordered them to set up an image in honor of the beast who was wounded by the sword and yet lived. 15 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.[a] That number is 666.
