The number of the beast is 666.
1 And the dragon stood on the shore of the sea. And I saw a beast coming out of the sea. He had ten horns and seven heads, with ten crowns on his horns, and on each head a blasphemous name. 2 The beast I saw resembled a leopard, but had feet like those of a bear and a mouth like that of a lion. The dragon gave the beast his power and his throne and great authority. 3 One of the heads of the beast seemed to have had a fatal wound, but the fatal wound had been healed. The whole world was astonished and followed the beast. 4 Men worshiped the dragon because he had given authority to the beast, and they also worshiped the beast and asked, “Who is like the beast? Who can make war against him?” 5 The beast was given a mouth to utter proud words and blasphemies and to exercise his authority for forty-two months. 6 He opened his mouth to blaspheme God, and to slander his name and his dwelling place and those who live in heaven. 7 He was given power to make war against the saints and to conquer them. And he 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 book of life belonging to the Lamb that was slain from the creation of the world. 9 He who has an ear, let him hear. 10 If anyone is to go into captivity, into captivity he will go. If anyone is to be killed with the sword, with the sword he will be killed. This calls for patient endurance and faithfulness on the part of the saints.
11 Then I saw another beast, coming out of the earth. He had two horns like a lamb, but he spoke like a dragon. 12 He exercised all the authority of the first beast on his behalf, and made the earth and its inhabitants worship the first beast, whose fatal wound had been healed. 13 And he performed great and miraculous signs, even causing fire to come down from heaven to earth in full view of men. 14 Because of the signs he was given power to do on behalf of the first beast, he deceived the inhabitants of the earth. He ordered them to set up an image in honor of the beast who was wounded by the sword and yet lived. 15 He was given power to give breath to the image of the first beast, so that it could speak and cause all who refused to worship the image to be killed. 16 He also forced everyone, small and great, rich and poor, free and slave, to receive a mark on his right hand or on his forehead, 17 so that no one could buy or sell unless he had the mark, which is the name of the beast or the number of his name. 18 This calls for wisdom. If anyone has insight, let him calculate the number of the beast, for it is man’s number. His number is 666.
1 Then I looked, and there before me was the Lamb, standing on Mount Zion, and with him 144,000 who had his name and his Father’s name written on their foreheads. 2 And I heard a sound from heaven like the roar of rushing waters and like a loud peal of thunder. The sound I heard was like that of harpists playing their harps. 3 And they sang a new song before the throne and before the four living creatures and the elders. No one could learn the song except the 144,000 who had been redeemed from the earth. 4 These are those who did not defile themselves with women, for they kept themselves pure. They follow the Lamb wherever he goes. They were purchased from among men and offered as firstfruits to God and the Lamb. 5 No lie was found in their mouths; they are blameless.
