1. The beast out of the sea with 7 heads, 10 horns and 10 crowns etc is the Political Global Government. The leader of that system is given power, throne and great authority by Satan.
2. The beast out of the earth is the second leader who oversees the economic and religious aspect of the Global Government. (see `worship` & mark to buy and sell, Rev. 13: 12 & 16 & 17).
You are still wrongly adding an extra head world leader in the Rev.13 when there is only one, i.e., the "dragon". You have not understood about the "dragon" per our Lord Jesus given through His Apostle John.
1. Rev.12:3-4 -- a beast kingdom of ten horns, seven heads, but only seven crowns is shown linked with the "red dragon" drawing a third of the stars (angels) to earth. That was Satan's original rebellion of old, in the previous world before Adam and Eve. The Rev.13 beast kingdom will have ten crowns instead of seven, showing the final beast kingdom will be a type of repeat of the one Satan originally rebelled against God with.
2. Rev.12:7-9: war in Heaven happens between Archangel Michael and his angels vs. Satan and his angels. Satan and his are cast out of Heaven. It tells us there will be no more place found for him in Heaven. That means he has... to appear here, in OUR dimension on this earth where we live.
3. Rev.12:9 -- we are shown the title of "dragon" is another one of Satan's many names.
4. Rev.12:10 -- because of Satan being cast out of heaven, then Salvation and the power of Christ will come there, in Heaven, because the 'accuser' of our brethren is cast down which accused us day and night before God's Throne. That reveals this casting out is for the end of days, and not past history.
5. Rev.12:14-17 -- after being cast out of heaven down to earth, the "dragon" goes after the symbolic 'woman' (God's people), and Lord Jesus uses Satan's titles of "serpent" and "dragon" interchangeably. This symbolic woman he goes after keep the commandments of God and have the Testimony of Jesus Christ, and represents Christ's faithful Church.
6. Rev.13:1-2 -- reveals another beast kingdom version similar to the one Satan rebelled with of old mentioned in Rev.12:3-4. This final beast kingdom that comes out of the "sea", the "waters" representing peoples, multitudes, nations, and tongues, will have ten crowns over it instead of seven like the original one.
7. Rev.13:3 -- this final world beast kingdom which is to have seven heads, are seven mountains per Rev.17, and one of the heads suffers a deadly wound that is healed and linked to the time when all the world will wonder after the beast (king).
8. Rev.17:8 -- reveals the beast that was and is not and shall ascend out of the bottomless pit and goes into perdition, with those on earth 'wondering' at that beast when they behold him as the beast that was, and is not, and yet is. That is the link to the Rev.13:3 beast kingdom having its deadly wound healed upon one of its seven heads.
The meaning is: Satan is known as a 'beast' also. That is also one of the titles of the beast king. He is over his dominion which is the 'beast kingdom'. Just as in Rev.17 one must differentiate when Scripture is referring to each beast type, this MUST be done in Rev.13 also. The beast kingdom does not... ascend out of the bottomless pit, Satan does. Satan is the beast that 'was' (time of old when he first rebelled in coveting God's Throne). Satan is the beast that 'is not' (Satan has not be upon a throne on earth again since God ended that old world when Satan first rebelled). Satan is the beast that "yet is" (this is the near future when Satan as the dragon will be cast down to earth and play Messiah in Jerusalem for the end prior to Christ's return. That is when he will setup this Rev.13:1 beast kingdom, which is what today's "one world government" movement is about.
9. Rev.13:11 forward -- the idea of the "another beast" having two horns 'like' a lamb is to represent a mimic of our Lord Jesus Christ. We know this "another beast" will be a fake Christ because Lord Jesus already warned us about him in Matthew 24:23-26. And that beast being shown speaking 'as a dragon' confirms this even more so, that it will be Satan himself, de facto on earth, trying to play God, and demanding all to bow to him in place of God. He will setup an 'image of the beast', pointing to what the king of Babylon did back in history during the days of Daniel with creating an idol image of gold for all to bow in worship to at the call to worship, or be killed. Thus the "another beast" represents a repeat role of the king of Babylon. No brainer, because Lord Jesus even gives us the label of Babylon for this endtime beast kingdom per Rev.17 & 18.
