From Hal Lindsey's Late Great Planet Earth:
Josephus the Historian said, "Magog is called the Scythians
by the Greeks." He said they lived in the northern regions
above the Caucasus mountains.
Pliny the Roman Historian noted that the Scythians were the
principle part of the people who make up modern Russia.
The Greek name "Moschi" derived from the Hebrew name
Meshech is the source of the name for the city of Moscow.
Tubal is from the founder of the Tibereni, a people dwelling
to the west of Moscow on the Black Sea.
German scholar Dr. Keil said of Rosh: "The Byzantine and
Arabic writers frequently mention a people called Ros and Rus,
dwelling in the country of Taurus, and reckoned among the
Scythian tribes."
