1. Sedei Chemed (quoting from the Chida) states that the idea that “it is forbidden to benefit” from material which appears miraculously, isn’t actually a prohibition — rather, it is a “midas chassidus — behaviour of the pious.” And with regard to the Mann, it was certainly not forbidden to benefit from it, because Hashem specifically did this miracle so the Jewish people would have what to eat, and it cannot be that he did this miracle for naught, (which would be the case if the Jewish people could not eat it.)
(2:) The author of Tiferes Yisroel writes (at the conclusion of Maseches Midos) that when in difficult circumstances, one may gain benefit from materials created miraculously. Based on this, we can explain that existing in the desert was considered difficult circumstances.
(3:) The author of Yad Dovid, writes at the conclusion of Maseches Taanis that the principle that we should not gain benefit from such materials only applies to an individual — but a plurality of people may benefit from such materials.
2. Rabbeinu Bechaye (on Beshalach, 15:20): (1:) Prophecy is first mentioned in the Torah with regard to Miryam. (2:) Avigayil was the first to call Olam Haba, “Tzror Hachayim — the bond of life,” (Shmuel I, 25:29.) (3:) We learn how to daven from Chana, (Shmuel I, 10:16.) (4:) We learn the idea of “gilgul — reincarnation” from a wise woman of Tekoa, (Shmuel II, 14:14.)
3. Gemoro, Sanhedrin, 56b: “The Jewish people were commanded [to observe] ten mitzvos in Mara: Seven that the descendants of Noach had accepted upon themselves — and [Hashem] added to them [the following mitzvos:] Judgement, and Shabbos, and honoring [one’s] father and mother.”
4. Rabi Sholom bar Yosef, one the great rabbonim of Yemen, wrote (in his sefer, Chemdas Yomim) that Moshe Rabbeinu took the bones of Basya with him to Eretz Yisroel, together with the bones of Yosef. This is what the extra word, “es — and” in the passuk “And Moshe took ‘es — the’ bones of Yosef” denotes; it is to indicate that also Basya’s bones were taken. The Medrash states that Moshe Rabbeinu had 10 names, but the Torah refers to him with the name Basya gave him, to honor her.
5. The author of Aruch Hashulchan states: “And this is why the Jewish people were commanded about Shabbos in 7 parshas of the Torah: In Beshalach, Yisro, Mishpatim, Ki Sisa, Vayakhel, Emor, [and] Va’eschanan. [This is] to indicate that all 7 days of the week are dependent on Shabbos.”
6. Targum Yonasan ben Uziel says on this passuk: “Amalek killed people from the tribe of Dan who had idol statues in their possession.” These were people who were not included in the clouds’ protection, because they served idols.
7. It tasted bitter to them. — Medrash Raba
8. Throughout history, seas and rivers split many times for the Jewish people: (1:) The splitting of the Reed (Red) Sea by Moshe Rabbeinu. (2:) The splitting of the Jordan River by Yehushua, (Yehoshua, 3:16.) (3:) Eliyahu, before he ascended to heaven, (Melochim II, 2:2.) (4:) Elisha, (ibid.) (5:) Rabi Pinchas ben Ya’ir, on his way to performing the mitzva of freeing captives, (Yerushalmi, Demai, 3:3.) (6:) Yaakov Avinu when he fled Eisav, (Tanchuma, Vayetze.)
9. Gemoro, Yuma, 75b: “At the beginning, the Jewish people were like chickens pecking at the garbage; [they grabbed and ate food whenever it was around,] until Moshe came and set specific times to eat [— he set mealtimes for them in the morning and in the evening.]”
10. This passuk: This is what Hashem has commanded: Gather as much of it as each of you requires to eat, an omer to a person for as many of you as there are; each of you shall fetch for those in his tent,” (16:16.) — Mechilta
