מדרש על דברי הימים א 1:7

"The descendants of Japheth: Gomer, Magog, Madai, Javan (Genesis 10:2)": Rabbi Samuel son of Ammi said: "This is Africa, Germania, Media, Macedonia Isania". "And Tiras": Rabbi Simon said: "This is Persia". The Rabbis said: "Thrace". "The descendants of Gomer: Ashkenaz, Riphath, and Togarmah (Genesis 10:3)": Asia, Adiabene, and Germania. Rabbi Berechya said: "Germanica". "The descendants of Javan: Elishah and Tarshish (Genesis 10:4)": Hellas, Italia, Dardania. One verse says: "the Dodanim" and a different verse says "the Rodanim (1 Chronicles 1:7)". Rabbi Simon and Rabbi Chanin: Rabbi Simon said: "Dodanim" because they are the children of the uncles [dodin] of Israel, Rodanim because they went and attack [rodin] them". Rabbi Chanina said: "When Israel was placed in a high position they came and said to them, we are the children of your uncle [dod-khen], and when they are placed in a low position they come and attack [rodin] them".
