The census in Bamidbar 26 is directed thus:
Take the sum of all the congregation of the children of Israel, from twenty years old and upward, by their fathers' houses, all that are able to go forth to war in Israel.'
In reporting this census, the torah tells us about women three times, where I would expect either zero (women don't go to war) or many more (despite any gender disproportions). The three cases are: the daughters of Tzelophehad; Serach bat Asher; and Yocheved and Miriam. Rashi says nothing about the first, points out that Serach is still alive (she also went into Egypt), and talks about Yocheved's conception but says nothing about why she and Miriam are mentioned here.
Are these women mentioned here just because they're the only "named" women we know about, so they're included out of a sense of completeness? Or did these women have some role in the planned conquest that calls for their mention here, in a pre-conquest census?
