TT #22 · Parashas Vayigash · Passuk 46:26
All the persons belonging to Yaakov who came to Egypt — his own issue, aside from the wives of Yaakov’s sons — all the persons numbered sixty-six.
Torah Temimah points to Piskei Mahari"V, Choshen Mishpat 247:3.
TT lemma: the sixty-six.
English: “His own issue” — from here it follows that one who says, “My property is for my descendants,” or “for those who come from my loins,” includes daughters as well, since Dinah was among the seventy souls and Scripture included her under “his own issue.”
Derash on the verse (midrashic accounting) — not a formal named middah of the 13.
Sixty-six of Yaakov’s descendants are listed before adding those already in Egypt or born on the way, yielding the traditional seventy.
