Sforno on Genesis 49:27/ספורנו על בראשית מ״ט:כ״ז

Binyamin’s rise to power also occurred at the dawn of Jewish monarchies in the person of King Sha-ul, and once more near the end of Jewish one man rule under Mordechai. Subsequently, there was never again a true Jewish political independence, and the religious leadership was in the hands of the אנשי כנסת הגדולה, a college of 120 elders.
