אֵ֣לֶּה בְנֵי־חָ֔ם לְמִשְׁפְּחֹתָ֖ם לִלְשֹֽׁנֹתָ֑ם בְּאַרְצֹתָ֖ם בְּגוֹיֵהֶֽם׃ (ס)
Tels sont les enfants de Cham, selon leurs familles et leur langage, selon leurs territoires et leurs peuplades.
Rashi on Genesis
ללשנתם בארצתם AFTER THEIR TONGUES, IN THEIR LANDS — Although these were of different tongues and lands they are nevertheless all sons of Ham.
Radak on Genesis
אלה, this has been explained already on 10,1.
