Easton's 1897 Bible Dictionary:
Scythian
   The Scythians consisted of "all the pastoral tribes who dwelt to
   the north of the Black Sea and the Caspian, and were scattered
   far away toward the east. Of this vast country but little was
   anciently known. Its modern representative is Russia, which, to
   a great extent, includes the same territories." They were the
   descendants of Japheth (Gen. 9:27). It appears that in apostolic
   times there were some of this people that embraced Christianity
   (Col. 3:11).
