From Joel C. Rosenberg book Epicenter, everything in quotes are his words.
"Page 83, The first thing we need to understand is that Gog is probably not actually a personal name, but more likely a title, like czar or pharaoh.
Thus, we are not looking for the rise of a specific person whose first or last name is Gog so much as a "prince" who will arise in "the land of Magog" (Ezekiel 38:15 NASB). In The Ezekiel Option, Dr. Eliezer Mordechai (a fictional former head of the Mossad, Israel's foreign intelligence agency) explains to Jon Bennett (a fictional senior White House advisor) that this means Gog is a political leader from a country due north of Israel. A quick check of any world map reveals that there are only five such countries today: Lebanon, Syria, Turkey, Ukraine, and Russia. The one farthest north, of course is Russia."
"Voltaire in his Philosophical Dictionary, noting that "it is incontestable that the inhabitant of Gaul and Spain are descended from Gomer, and the Russians from Magog, his younger brother." Interestingly enough, the genealogical tree to which he referred actually finds its origin in the very Bible for which he had so little regard. Magog is first mentioned in Genesis 10-Magog was a son of Japheth, who was a son of Noah (he of Noah's-ark fame)."
"Here the Roman historian Josephus can offer us another clue. In The Antiquities of the Jews, his twenty-volume classic written in the first century after Christ, Josephus wrote of the descendants of Noah: "After [attempting to build the tower of Babel-see Genesis 11] they were dispersed abroad, on account of their languages, and went out by colonies everywhere; and each colony took possession of that land which they lighy upon and unto which God led them.... Magog founded those that from him were named Magogites, but who are by the Greeks called Scythians."
"The Scythians, genetically were Aryans. Geographically, they lived in the areas now known as Russia, the former Soviet republics, and central Asia. One referece work describes a Scythian as a "member of a nomadic people orginally of Iranian stock who migrated from Central Asia to southern Russia in the 8th and 7th centuries B.C.... Scthians founded a rich, powerful empire that survived for several centuries."
Rosh, Meshech, And Tubal:
"This brings us to the next big question: where are "Rosh, Meshech and Tubal," of which Gog is prince"? A study of ancient Hebrew, ancient history, and modern-day geography points us to Russia, Moscow, and Tobolsk (in Siberia), respectively. The word Rosh in Hebrew can mean "head" or "cheif," leading some scholars to the conclusion that Gog is the "cheif prince" of Meshech and Tubal. But both the Septuagint and the Masretic Text, two of the oldest and most reliable copies of the Holy Scriptures, translate Rosh as the proper name of a geological place. The Septuagint is the oldest Greek translation of the Hebrew Scriptures."
"In his seminal work Gesenius' Hebrew-Chaldee Lexicon to the Old Testament, William Gesenius- the father of modern Hebrew lexicography (the science behind compiling dictionaries)-concluded that the Rosh to which Ezekiel refers is a proper name. He also concluded that Rosh is "undoubtedly the Russians, who are mentioned by the Byzantine writers of the tenth century, under the name of Ros, dwelling to the north of Taurus [in Turkey]."
