וַיַּעֲשׂ֥וּ מִלְחָמָ֖ה עִם־הַֽהַגְרִיאִ֑ים וִיט֥וּר וְנָפִ֖ישׁ וְנוֹדָֽב׃
I walczyli z Hagritami, z Jeturem, Nafiszem i Nodabem.

שנים עשר נשיאים לאומתם, twelve princes corresponding to the number of their families (tribes). Each one of the ones named by the Torah was a tribal chief, member of a family which grew into a mighty tribe bearing the name of their first founder. We find further detailed examples of these tribes in Chronicles I 5,19. A number of these tribes have been mentioned in different contexts in the Books of the Prophets.
