The story of Tzelofhad's daughters introduces five sisters who turn to the patriarchal leadership seeking to preserve the name of their deceased father. Their claim - "why should our father's name be omitted" (למה יגרע שם אבינו) parallels another claim brought in an earlier chapter of BeMidbar. The people who were impure due to contact with the dead approach Moshe with the same terminology - למה נגרע - regarding their inability to offer the Pessah sacrifice due to their impure state. The link between the two stories leads to the conclusion that Tzelofhad's daughters are correct, and their positive initiative is accepted.
