Komentarz do Diwrej ha-jamim I 1:7

And the sons of Javan: Elisha The reason he did not mention Magog and Madai is that he mentioned only the lineage of these, but he did not mention the sons of Magog or the sons of Madai or the rest because heads of nations did not emerge from them, but all their nations were called by the name of Kittim and Dodanim.

and Rodanim And further (Gen. 10:4) Scripture states: “and Dodanim.” When Israel sins, they come and rule over them (רוֹדִים), but when Israel is in power, they say, “You are the sons of our uncles (דּוֹדֵינוּ).” At first they appeared as friends when it was for their own benefit, but later they subjugated them.
