japhet

And he said unto Japhet, "Be thou servant to Shem my heir, and be thou subject unto him."

And when the sons of Noah, Shem, and Ham, and Japhet, divided the world among them, they looked on thy country with wisdom and saw that, although it was spacious and broad, it was a land of whirlwind and burning heat, and [therefore] gave it to Canaan, the son of Ham, as a portion for himself and his seed for ever.

The kingdom of Rome was the portion and dominion of Japhet, the son of Noah.

And be [fore]saw what would come after, and that the kingdom would not remain to the children of Japhet, but would depart to the seed of David, of the tribe of Shem.

And the city of Rome became the possession of `Adrami and of his generations after him, for by the Will of God the whole of the kingdom of the world was given to the seed of Shem, and slavery to the seed of Ham, and the handicrafts to the seed of Japhet.
