Seeing as the mountain was 'Har N'vo' (as recorded in Devarim 32:49, 34:1), why does the Torah here call it "Har ha'Avarim"?
Ramban: Because it was situated by the crossings of the Yarden, and it is from this point that they actually crossed into Eretz Kena'an. 1
Why did Hashem see fit to add the words "Ka'asher Meis Aharon Achicha"?
Rashi #1: From here we see that Moshe coveted the same death as Aharon. 1
Rashi #2: It is to inform him that, since it was decreed that both of them could not enter Eretz Yisrael because they had sinned by failing to sanctify Hashem's Name 2 and Aharon had died in the desert, Moshe was no better than him, and he must therefore die too.
Why, whenever the Torah mentions Moshe and Aharon's death, does it always see fit to mention the reason why they died?
Rashi: Because Moshe requested it, lest people think that they did not enter Eretz Yisrael due to a lack of Emunah, like the rest of the generation that left Egypt. 1 The Torah therefore fulfilled his request, to let people know that this was their only sin. 2
Rashi: It can be compared to two women who received lashes in Beis-Din, one for Zenus , and the other for eating unripe figs of Shemitah (See Sifsei Chachamim). The latter requested of Beis-Din to announce her sin, so that people should not accuse her of the more severe sin of Zenus.
Rashi writes that this is like two women lashed in Beis-Din, one for Zenus, and one for eating unripe figs of Shemitah. What is the case in which one is lashed for these?
Moshav Zekenim (14): If there are no witnesses and warning for Zenus, 1 Beis Din lashes her. Shemitah Peros are "l'Achlah", and not to be wasted. One must wait until they are ripe. Even though a Lav derived from an Aseh is an Aseh, she is lashed mid'Rabanan for transgressing an Aseh.
Why does he say that there were not witnesses and warning? If she is married, she is Chayav Misah, and there are no Torah lashes. If she is single, there are Torah lashes for Zenus with Chayavei Lavim, only through witnesses and warning! If there are no witnesses. Beis Din does not lash based on one's admission! Lehoros Nasan (10:92:2) discusses whether this is even for lashes mid'Rabanan. (PF)
