and upon his horns ten diadems, and upon his heads names of blasphemy.
Revelation 13:2 – And the beast of prey which I saw, was like a leopard;
and his feet like [those] of a wolf, and his mouth like the mouth of lions:
and the dragon gave to him his own power and his throne, and great authority.
Revelation 13:3 – And one of his heads was wounded as it were to death;
and his deadly wound was healed.
And all the earth wondered after the beast of prey.
Revelation 13:4 – And they worshipped the dragon, because he had given authority to this beast of prey, and [they said], who can make war upon him ?
Revelation 13:5 – And there was given to him a mouth speaking great things, and blasphemies:
and authority was given him to operate forty and two months.
Revelation 13:6 – And he opened his mouth in blasphemy towards God, to blaspheme his name and his tabernacle, and them who dwell in heaven.
Revelation 13:7 – And authority was given him over every tribe and people and tongue and nation:
and it was given him to wage war with the saints, and to overcome them.
Revelation 13:8 – And all that dwell on the earth, whose names are not written in the book of life of the Lamb slain from the foundation of the world, will worship him.
Revelation 13:9 – If any one hath ears, let him hear.
Revelation 13:10 – If [any one] carrieth into captivity, he shall himself go into captivity;
and if any one slayeth with the sword, he must be slain with the sword:
here is the patience and the faith of the saints.
Revelation 13:11 – And I saw another beast of prey, which came out of the earth;
and he had two horns like those of a lamb, and he spoke like the dragon.
Revelation 13:12 – And before him he exercised all the authority of the first beast of prey, whose deadly wound was healed.
Revelation 13:13 – And he wrought great signs, even so as to make fire come down from heaven upon the earth, before men.
Revelation 13:14 – And he seduced them that dwell on the earth, to erect an image to the beast of prey who had the wound from a sword and recovered.
Revelation 13:15 – And it was given him to put life into the image of the beast of prey;
and to cause that all they who would not worship the image of the beast of prey, should be slain:
Revelation 13:16 – and to cause that all, great and small, rich and poor, bond and free, should receive a mark on their right hands, or upon their foreheads;
Revelation 13:17 – so that no one might be able to buy or to sell, except those who had the mark of the name of the beast of prey, or the number of his name.
Revelation 13:18 – Here is wisdom:
let him that hath intelligence, compute the number of the beast of prey;
for it is the number of a man:
and its number is six hundred and sixty and six*.
* Oldest mss say 616 not 666.
My view is that 616 is Gog – who has always been the Beast in Prophecy.
