Idź, a zgromadź starszych Israela i powiedz im: Wiekuisty, Bóg ojców waszych, objawił mi się, Bóg Abrahama, Ic'haka i Jakóba, i rzekł: Wejrzałem na was i na to co uczyniono wam w Micraim.
Rashi
את זקני ישראל THE ELDERS OF ISRAEL, those singled out to attend meetings, (i. e. the leaders) (cf. Yoma 28b). If, however, you should say that the text means old men in the ordinary sense I ask: How was it possible for him to gather all the old men amongst a male population of 600,000?
Chizkuni
את זקני ישראל, “the elders of the people of Israel.” Rashi understands the word: זקני here as referring to the “elders” in the sense of the leading sages; he adds that it would have been impossible for Moses to assemble all the aged people in a nation of over 600000. Exodus 4,29, where a similar assembly is reported must be understood in the same way.
