Didn't Dye In Vain

What was the great merit of the daughters of Zelophehad that they merited a parsha to be written in their sake?  Rav Simcha Zissel Broide suggested it not as most think that it is the daughter's of Zelophehad's actions that merited a parsha to be written in the Torah, rather it is the act of Zelophehad himself.  As Rashi notes, he was the the מקושש עצים who desecrated the Shabbos for noble purposes to show the harshness of violating Shabbos.  The act of Zelophehad was a true act of מסירות נפש.  He lost all of his עולם הבא just to teach a lesson.  Says Rav Simcha Zissel, it is because it was such a great act of מסירות נפש, even though he was culpable for his actions, that merits that a parsha is given his name.  He points out the parsha doesn't bear the names of the daughter's of Zelophehad , rather that of Zelophehad, the parsha of the בנות צלפחד.
Based upon this idea the Shlal Rav adds the Gemorah Sanhedrin (8a) says ראויה פרשת נחלות שתיכתב על ידי משה רבינו אלא שזכו בנות צלפחד ונכתב על ידן ראויה היתה פרשת מקושש שתיכתב ע"י משה רבינו אלא שנתחייב מקושש ונכתבה על ידו ללמדך שמגלגלין חובה ע"י חייב וזכות על ידי זכאי.  Why does it mention the בנות צלפחד before the מקושש, if the episode of the מקושש is first?  Because the Gemorah is explaining the merit of the בנות צלפחד was from their father; what was his merit?  Because he was the מקושש and although that was an act of חובה, it was an act of זכות as well.  The Gemorah means one act can contain an element of חובה and an element of זכות that are both noteworthy.
