As is well-known, Hashem created the world once, and from then, there are no new creations. How does that fit with the creation of the Manna?
Why does the Torah use the word "Mamtir" regarding the Manna?
Ramban #2 (citing Targum Onkelos) and Targum Yonasan: It means simply to bring it down.
Ramban #3: "Matar" and all its derivatives stem from the Lashon "Matara le'Chetz" - a target for the arrow - because whatever Hashem shoots down from the sky is comparable to an arrow that one shoots at the target. 3
Why does the Torah refer to the Manna as "Lechem"?
Ramban (citing Ibn Ezra and R'dak): The Torah refers to all food as Lechem. 3
And all kinds of loaves are called bread, irrespective of the ingredients (Ramban).
Why does the Torah not mention the meat here, as it does in Pasuk 8?
Ramban: When recording a command and its execution, it is the way of The Torah to mention one of them and to omit the other. 1
What test is the Pasuk referring to this time?
Rashi: To see whether they would adhere to the various Mitzvos connected with the Manna 1 - not to leave any of it over until the morning, and not to go out on Shabbos to collect it.
Ramban: Hashem tested them whether they would follow Him despite the fact that the Manna (of which they had never heard before) appeared only on a daily basis, and they never had food for the next day. 2
Rashbam: Since every day on an ongoing basis, they had to raise their eyes Heavenwards for their food, their Emunah in Hashem would increase. 3
Seforno: To see whether now, that they were receiving their sustenance without any effort on their part, they would go in the way of the Torah. 4
See Sifsei Chachamim.
As the Mechilta states 'The Torah was only given to those who ate the Manna (since they had nothing to distract them from keeping it [Seforno]).
