And I stood upon the sands of the sea, and I saw a beast rise up out of the sea, having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy.
and four great beasts came up from the sea, diverse one from another.
And he (the angel) said, the fourth beast will be the fourth kingdom on earth, which shall be diverse from all kingdoms, and shall devour the whole earth, and shall tread it down and break it in pieces. And the ten horns out of this kingdom are ten kings that shall arise: and another shall rise after them....
The antichrist kingdom that rises from the sea in the Revelation prophecy is described as a beast who has seven heads and ten horns. The beast has the genetic makeup of the lion, the bear and the leopard and has the ten horns of the fourth beast kingdom.
And the beast which I saw was like unto a leopard, and his feet were as the feet of a bear, and his mouth as the mouth of a lion....
The lion, the bear and the leopard represent three beast kingdoms that ruled over the middle east: Babylon the lion, Medo-Persia the bear and the Grecian empire representing the leopard. This tells us the location of the rising beast kingdom.
The seven heads represent the four individual beast kingdoms from Daniel's prophecy, the lion, bear and leopard, and the beast with ten horns. There are three additional kingdoms which were not beast kingdoms: Egypt, Assyria and Rome, which make a total of seven heads or seven world empires. These world kingdoms are attached to the beast as 'heads' similar to the beast kingdom 'like a leopard' that had four heads- Daniel 7:6. The beast from the sea in Revelation 13 is 'like the leopard' which had four kingdoms represented as four heads. Instead of four heads or four kingdoms, this beast has a total of seven heads or, seven kingdoms.
