Sorry about the length.
Rev 12:3 the other sign John saw was a great red dragon meaning Satan. Remember, this is a vision and a sign as Satan has not yet been cast out of heaven until the beginning of the 3 1/2 years of the greatest tribulation we will ever see nor ever see again, Matthew 24:21. The description of the dragon being great and red depicts its nature and character as being fierce and murderous, John 8:44. This red dragon is depicted as having seven heads, ten horns, and seven crowns upon his heads. This is also confirmed in Rev 17 as mystery Babylon is described. The seven heads and ten horns refer to the original ten kingdoms of which three were subdued by the little horn of Daniel 7:8. The last kingdom which stands greater than all the others is that of a revived Roman Empire that takes control over all the ten nations who then implements a deceiving peace treaty with the Muslims in which the Dome of the Rock will be given over to the son of perdition as he reigns from the very Temple mount of God, meaning the holy place in Matthew 24:15. This is the abomination Jesus spoke of in Matthew 24:15, 16 that we are to flee from when we see the son of perdition take his seat in Jerusalem for 3 1/2 years.
Rev 13 the beast rises up out of the sea as the sea here is symbolic of people and nations as in a sea of humanity, Daniel Chapter 7:1-8; Revelation 17:15. This beast is a Luciferian system that controls world wide economics, political, military, educational, environmental and false religious system. This beast system that Satan works through gives its power to the beast out of the earth as the beast out of the earth appears as the Lamb of God, but is a false Christ being the son of perdition, 2 Thessalonians 2:3-12, with two horns. The two horns represent the Old Roman Empire that received its deadly wound back in 1798 by General Berthier who made his entrance into Rome and abolished the Roman government and established a secular one. That caused them to scatter into the other ten nations (ten horns). The wound was healed in 1929 by Mussolini.
God speaks to us in scripture of a 3 1/2 year tribulation during the time of the seventh trumpet sounding, not a seven year tribulation, as being time, times and half time which equals 1260 days = 3 years or 3 Times Hebrew calendar only had 30 days for each month and this is where you get 1260 days or 3 years.
[Scripture reference]
Revelation 12:14; Daniel 7:25; Daniel 12:7
1260 days Revelation 11:3; Revelation 12:6
42 months Revelation 11:2; Revelation 13:5
No where in scripture does it mention a seven year tribulation, but only seven trumpets of God's fierce wrath as scripture says we will always have tribulations as the last time will be such as was not since the beginning of the world to this time, no, nor ever shall be, Matthew 24:21; Deut 4:30; 7:19; 29:1-6; 1 Samuel 26:24; Matthew; John 16:33; Romans 12:12; 24:21; James 1:2; 1 Peter 1:6.
Below is that of the seven remaining nations described as four beasts in Daniel 7:1-8 and the three kingdoms that were subdued by the little horn, which is the Roman Empire.
The three kingdoms that were subdued by the little horn of Daniel 7:24 are the Heruli, Vandals, and Ostrogoths who were eliminated by the year 538 AD under the leadership of the Eastern Roman Emperor Justinian whose deadly wound came in 1798.
Seven remaining nations that still exist today:
Babylonian Empire:
(Iraq) The lion represents the winged lions that guarded the royal places of Babylon. This Empire ran from 2000BC - 1759BC
Medo Persian Empire:
(Iran) The ribs of the bear are part of the consuming greed that devours the first empire.
Grecian Empire:
(Greece, Turkey, Syria, Egypt) Four wings of the leopard described the swiftness of this empire that ran from 334-331BC. It wrestled world dominion from Medo-Persia. After the death of Alexander the Great the kingdom was divided into four minor kingdoms that continued as prominent factors in world politics until the Roman Empire gathered it back as one kingdom.
Roman Empire: (little horn, Daniel 8:9-14, 23-27)
Iron represents the stronghold this nation had. Daniel chapter 2 mentions the iron element of this empire that it to will be divided and broken as God will set up a kingdom that will never be destroyed.
This Empire ran from 753BC -27BC
The seven heads are that of the Babylonian Empire, Medo/Persian Empire, Grecian Empire and Roman Empire. The ten horns represent the nations the Roman Empire scattered to when the deadly wound was put upon them, Daniel 7:23-25; Rev 13:3. The deadly wound came in 1798 when General Berthier of France, who made his entrance into Rome, abolished the Roman government and established a secular one and captured Pope Pius VI, who soon died in captivity in Valence, on August 29, 1799. In 1801 Napoleon made an agreement with Pope Pius II establishing Napoleon's Organic Articles of granting the Tribunal and the Corps legislative partial control of the concordat in order to help the state monitor any politically harmful Catholic or Protestant movements or activities. The wound was largely healed in 1929 when Mussolini gave the Vatican back to Pope Pius XI and established it as a country in it's own right in the Lateran Treaty.
The Roman Empire was founded in 31BC when Augustus Caesar proclaimed himself the first emperor of Rome and came to an end with the fall of Constantinople in 1453CE. Rome controlled over two million square miles stretching from the Rhine River to Egypt and from Britain (England) to Asia Minor which made up the Grecian Empire of Greece, Turkey, Syria and Egypt. In 146BC the Romans destroyed Corinth during the Battle of Corinth and made the Greece Empire into a province of the Roman Empire. This timeline goes from 753BC to 27BC. Nero burned Rome in 64AD and blamed the Christian community in the city causing the Roman Empires first persecution of Christians. In 1453 was the rise of the Ottoman Empire that conquered Constantinople destroying the Byzantine Empire (Eastern Roman Empire) that reigned from 330AD to 1453AD. The Roman Empire was divided into an eastern half and a western half in 285 CE by Emperor Diocletian. It was the Emperor Constantine in 330CE who moved the capital of the Roman Empire to Byzantium (Constantinople) in the Eastern Empire. The Roman Empire was then called the Holy Roman Empire that was a political entity beginning in 800AD - 1806AD from the time of Charlemagne (Holy Roman Emperor) who protected Pope Leo III from Adrian's supporters in Rome to Francis II, King of France. Pope Pius VII was the Pope from 1800-1823. The Roman Empire is known today as Vatican City, a city-state surrounded by Rome in Italy who has diplomatic relations with every nation around the world.
The crowns on its heads show that this dragon claims royal authority against the true King who is God of all creation as he prepares to take his seat above all that which is Gods Kingdom claiming he is God as he prepares to deceive the world through that of an existing Roman Empire, Daniel 8:9-12; Isaiah 14:12-15.
The beast rises up out of the sea, Rev 13, as the sea here is symbolic of people and nations as in a sea of humanity, Daniel Chapter 7:1-8; Revelation 17:15. The seven heads are that of the Babylonian Empire, Medo/Persian Empire, Grecian Empire and Roman Empire. The ten horns/nations represent the nations the Roman Empire scattered to when the deadly wound was put upon them, Daniel 7:15-28.
These ten nations were the Anglo-Saxons (Germans in Great Britain), the Franks (French), Suevi (Portuguese), Visigoths (Spanish), Burgundians (Swiss), Alemanni (Germans), Lombards (Italians), Ostrogoths, Heruli, and the Vandals in northern Africa. The last three being Ostrogoths, Heruli, and the Vandals had already been destroyed by the Roman Empire before their deadly wound came in 1798.
The beast out of the earth, Rev 13:11-18, is the revived Roman Empire (mystery Babylon, Rev 17:5) which causes man to take its mark. Daniel 7:25 and another shall rise after them; and he shall be diverse from the first, He will think to change times and laws: and they shall be given into his hand until a time and times and the dividing of time, 2 Thessalonians 2:13-12.
The ten horns are ten kings who have not yet received their kingdoms as the Vatican's New World Order Headquarters and the United Nations Organization, One Security Council that claims authority over the world are waiting for ten permanent members. In 2009 the UNO divided the world into ten economic regions and each one will have a Jesuit Provincial set over them, but their end will come with the glory of the Lord striking them down when He returns with us His army. (Will study more about the army in Rev 19)
