לעולם בתי אבות קא חשיב והא קא משמע לן דבנות צלפחד נטלו חלק בכורה אלמא א"י מוחזקת היא

The Gemara answers: Actually, the verse is counting fathers’ houses. And by also counting the inheritance of Zelophehad’s daughters, the verse teaches us this: That the daughters of Zelophehad took the portion of the firstborn due their father. Evidently, Eretz Yisrael is considered already in possession of one who was entitled to his portion of the land, even before the land was assigned. Although a firstborn son does not take a double portion of the property due to his deceased father as he does the property his father possessed, it is considered that Hepher possessed the portion that would eventually be assigned to him, and that Zelophehad was entitled to a double portion.

אמר מר והבנים נטלו בזכות אבי אביהם ובזכות אבי אמותיהן והתניא בזכות עצמן לא קשיא הא כמאן דאמר ליוצאי מצרים הא כמאן דאמר לבאי הארץ

§ The Gemara continues its discussion of the baraita. The Master says: And the sons of the spies and of the protesters took portions of the land in the merit of their paternal grandfathers and in the merit of their maternal grandfathers if those grandfathers were among those who left Egypt. The Gemara asks: But isn’t it taught in a baraita (Tosefta 7:10): The sons of the spies and of the protesters took portions in their own merit? The Gemara answers: This is not difficult: This baraita, which states they took portions in the merit of their grandfathers, is written in accordance with the opinion of the one who says that Eretz Yisrael was divided among those who left Egypt; and that baraita, which states that they took portions in their own merit, is written in accordance with the opinion of the one who says that Eretz Yisrael was divided among those who entered Eretz Yisrael.

ואיבעית אימא הא והא לבאי הארץ ולא קשיא הא דהוה בן עשרים הא דלא הוה בן עשרים:

The Gemara suggests another answer. And if you wish, say instead: This baraita and that baraita are written in accordance with the opinion that asserts that Eretz Yisrael was divided among those who entered Eretz Yisrael, and it is not difficult: This baraita is discussing one who was twenty years old when the Jewish people entered Eretz Yisrael, and therefore he took a portion in his own merit, and that baraita is discussing one who was not twenty years old.

ושהיה בכור נוטל שני חלקים: ואמאי ראוי הוא ואין הבכור נוטל בראוי כבמוחזק אמר רב יהודה אמר שמואל ביתדות אהלים

§ The mishna teaches: And Zelophehad took an additional portion that he received from Hepher, because he was a firstborn, and a firstborn takes two portions of inheritance from his father. The Gemara asks: But why was he entitled to the double portion of the firstborn? His portion of land is property merely due to Hepher, as Hepher never actually possessed the land, and the halakha is that a firstborn does not take a double portion of property due to the deceased as he does of property the deceased possessed. Rav Yehuda says that Shmuel says: This clause of the mishna is stated with regard to tent pegs and other assorted movable property that Hepher possessed.

מתיב רבה רבי יהודה אומר בנות צלפחד נטלו ד' חלקים שנאמר (יהושע יז, ה) ויפלו חבלי מנשה עשרה אלא אמר רבה ארץ ישראל מוחזקת היא

Rabba raises an objection from a baraita: Rabbi Yehuda says: The daughters of Zelophehad took four parts, as it is stated: “And ten parts fell to Manasseh” (Joshua 17:5). Clearly, this is referring to portions of land, and not simply movable property. Rather, Rabba says: Eretz Yisrael is considered already in possession of one who was entitled to his portion of inheritance land, even before the land was assigned.

מיתיבי אמר רבי חידקא שמעון השקמוני היה לי חבר מתלמידי רבי עקיבא וכך היה רבי שמעון השקמוני אומר יודע היה משה רבינו שבנות צלפחד יורשות הן אבל לא היה יודע אם נוטלות חלק בכורה אם לאו

The Gemara raises an objection from a baraita. Rabbi Ḥideka said: Shimon HaShikmoni was my colleague among the students of Rabbi Akiva, and so would Rabbi Shimon HaShikmoni say: Even before turning to God for guidance, Moses our teacher knew that the daughters of Zelophehad were inheritors and that they were entitled to their father’s portion, as well as his share in Hepher’s portion. But he did not know if they were entitled to take a portion of the firstborn of Hepher’s portion or not.

וראויה היתה פרשת נחלות ליכתב על ידי משה אלא שזכו בנות צלפחד ונכתבה על ידן

Rabbi Ḥideka continues citing Rabbi Shimon HaShikmoni: And the Torah portion concerning the laws of inheritances was fit to have been written through God initiating a commandment to Moses, without mentioning Zelophehad’s daughters. But by demonstrating their desire for land in Eretz Yisrael the daughters of Zelophehad merited that the portion was written through a response to them.
