It is written in Genesis: "The sons of Japheth: Gomer, and Magog, and Madai, and Javan, and Tubal, and Meshech, and Tiras. and the sons of Gomer: Ashkenaz, and Riphath, and Togarmah. And the sons of Javan: Elishah, and Tarshish, Kittim, and Dodanim. By these were the Isles of the Gentile divided in their lands everyone after his tongue, after their families, in their nations." (Gen 10:2-5)
In the Bible, Japheth is ascribed seven sons and seven named grandsons:
The intended ethnic identity of these 'descendants of Japheth' is not certain; however, over history, they have been identified by Biblical scholars with various historical nations who were deemed to be descendants of Japheth and his sons — a practice dating back at least to the classical encounters of Jew with Hellene, for example in Whiston). Josephus wrote:
- Japhet, the son of Noah, had seven sons: they inhabited so, that, beginning at the mountains Taurus and Amanus, they proceeded along Asia, as far as the river Tanais (Don), and along Europe to Cadiz; and settling themselves on the lands which they light upon, which none had inhabited before, they called the nations by their own names.
Josephus detailed the nations supposed to have descended from the seven sons of Japheth.
