창세기 10:13 미드라쉬: Midrash Tanchuma & Bereshit Rabbah

Another explanation. Why did Scripture concern itself with the genealogy of the chiefs? Did the Holy One, blessed be He, have nothing else to write about other than the chief of Timna, the chief of Lotan, etc.? He did so to teach us that from the very beginning of the creation of the world, the Holy One, blessed be He, concerned himself with the genealogies of the idolatrous nations so that it would not be left to them to describe for mankind their sterility and their degeneracy. How did He do that? When He came to the genealogy of the sons of Ham, He said: The sons of Ham: Cush, and Mizraim … and Cush begot Nimrod (Gen. 10:6–8); thus He indicated that they had become defiant, as it is said: He began to be a mighty one in the earth (ibid., v. 8). Similarly, when He said: And Mizraim begot Ludim … whence went forth (ibid., vv. 13–14), He did not say “he bore him” but he went forth, thereby informing us that he was the product of an incestuous relationship.

“And Mitzrayim begot Ludim, and Anamim, and Lehavim, and Naftuḥim” (Genesis 10:13).
“And Mitzrayim begot Ludim…” – all of the coinages of Egypt are only with yam:¹⁹All the sons of Mitzrayim had names ending in yud mem, which spells yam [the sea]. Ludim – the Ludim of the sea [Ludei yam], Anamim – the Anamim of the sea [Anamei yam], as their names imply, Lehavim – the Lahav of the sea [Lahav yam], Naftuḥim – the Naftuḥim of the sea [Naftuḥei yam].²⁰All these nations lived by the sea.
“And Patrusim, and Kasluḥim, from which the Philistines and the Kaftorim emerged” (Genesis 10:14).
“Patrusim” – Parvitot. “Kasluḥim” – Pekusim. Rabbi Abba bar Kahana said: Patrusim and Kasluḥim produced bachelors, these would steal the wives of those, and those would steal the wives of these. What emerged from them? Philistines – mighty,²¹They would invade [poleshim] other lands. Kaftorim – dwarfs.²²They were small and round like buttons [kaftorim].
