Most Talmudic sources identify Meshekh with Mysia (see Targum Yonathan; Targum on 1 Chronicles 1:5; Yerushalmi, Megillah 1:9; Yoma 10a; Buber on Pesikta Zutratha 26a) to the west of Bithynia near the Dodanim and Marmara Sea (cf. Yov'loth 9:12; Herodotus 7:42,74). Josephus, however, associates Meshekh with Cappadocia, whose capital is Mazaka, in what is now central Turkey (see Herodotus 1:72). Another possibility would be to identify Meshekh with the Massagatae, an ancient people who lived in Russia to the east of the Aral Sea (cf. Herodotus 1:201). It was these people who drove the Scythians into Cimeria (Ibid. 4:11) synonymous with the Moschians mentioned in ancient sources (Herodotus 7:78) who gave their name to the Muskeva River and Meshkhetians (who were persecuted ruthlessly by Stalin), and hence to Moscow before the arrival of the Slavs (Kesseth HaSofer)..
The Archangel of the Meshekhite nation will be with the armies of the four corners of the world in the final battle at the end of the world.
cf. Ezekiel 38:2, 27:13; Psalms 120:5.
