And the sons of Dan: Chushim.
Torah Temimah points to Bava Basra 143b.
TT lemma: ובני דן חשים.
English: “And the sons of Dan: Chushim” — the school of Chizkiyah taught: they were numerous like the shoots of a reed.
Derash on the verse (midrashic genealogy) — not a formal named middah of the 13.
Dan’s contribution to the seventy is represented by his son Chushim, listed in the plural pattern of the other tribes.
