Javan, Tubal, and Meshech, they were thy merchants: they traded the persons of men and vessels of brass in thy market.
Javan - the Ionians or Greeks; because the Ionians of Asia Minor were the first Greeks whom the Asiatics came in contact with.
Tubal and Meshech - the Tibareni and Moschi in the mountain-region between the Black and Caspian seas.
They traded the persons of men - i:e, as slaves. So the Turkish harems are supplied with female slaves from Circassia and Georgia.
And vessels of brass - all kinds of articles or implements of copper. Superior weapons are still manufactured in the Caucasus region.
