Genesis 2:10-14 teaches us of the four rivers that went out of Eden that turned into four heads. If you look on a map you will see where these rivers are located in modern day Turkey, Iran, Iraq down to the Persian Gulf. Eden is around Turkey, but hidden from us.
Four rivers:
Pison - Havilah SW Arabian Peninsula
Gihon - Ethiopia
Hiddekel - east of Assyria
Euphrates - SE Turkey down to the Persian Gulf
The battle of Armageddon is different than that of Ezekiel 38-39.
Rev 16:13 And I saw three unclean spirits like frogs come out of the mouth of the dragon, and out of the mouth of the beast, and out of the mouth of the false prophet.
Rev 16:14 For they are the spirits of devils, working miracles, which go forth unto the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty.
Rev 16:15 Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame.
Rev 16:16 And he gathered them together into a place called in the Hebrew tongue Armageddon.
There are ten nations that will compass the camp of the saints about, and the beloved city: and fire will come down from God out of heaven, and devour them, Rev 20:7-10.
These 10 nations of Ezekiel 38-39 wars consisted of, Rosh, Magog, Tubal, Meshech, Gomer, Togarmah, Persia, Put, Ethiopia and Sheba & Dedan.
Rev 20:7-10 Battle of Armageddon that we read about in Rev 16, happens when Christ returns to Earth with the saints that have been gathered up to Him, 1Thessalonians 4:13-18. These are the countries that come against Israel being present day Russia, Turkey, Syria, Iran, Iraq, Egypt, Saudi Arabia that make up the ten nations of Ezekiel 38-39.
