כלי יקר — איש איש למטה איש ראש לבית אבתיו הוא

Q — Why does the Torah add 'איש ראש לבית אבתיו הוא' after already calling each of the nesi'im 'איש איש למטה'? Isn't this redundant?

A — Kli Yakar reads the addition as a character qualification, parallel to Yaakov's blessing 'דן ידין עמו כאחד שבטי ישראל' — Dan would not favor his own tribe but would judge them 'like any other of the tribes of Yisrael.' Each nasi was a real leader 'איש למטה' — he asserted authority over his whole tribe. But the addition 'איש ראש לבית אבתיו הוא' goes further: even toward his own close family, his nearest kin, he led with the same impartiality. The verse selects leaders who do not bend the law for blood — the requirement isn't competence, it's freedom from favoritism.
