See Sifsei Chachamim.
Seeing as Aharon had not yet been chosen to be the Kohen Gadol ? moreover, we still find that Moshe served as Kohen Gadol ? during the Shiv'as Y'mei ha'MIlu'im - why did Moshe himself not place the bottle of Manna?
Refer to 16:33:1:1.
R. Bachye: It was a hint that Aharon and the Kohanim, who were destined to teach Torah to Yisrael, would be comfortably sustained ? like Yisrael in the desert via the Manna ? seeing as the Torah, which sustains the Neshamah, stems from Chochmah, "ve'ha'Chochmah Techayeh Ba'alehah". 1
Koheles 7:12. See R. Bachye who elaborates.
How could Moshe place the jar of Manna in front of the Aron, "Lifnei Hashem" (see Sifsei Chachamim]), seeing as the Mishkan with its Keilim had not yet been built?
Rashi and Rashbam: This Pasuk was actually said only after the Mishkan had been built, and it inserts it here 1 because it belongs to the Parshah of Manna.

What is the definition of "Tzintzenes"?

QUESTIONS ON RASHI
Rashi writes: "Tzintzenes - an earthenware flask." Why need Rashi tell us this?
Gur Aryeh: The doubled root (Tzadi-Nun-Tzadi-Nun) indicates that the word "Tzintzenes" is not merely a name; rather, it has some inherent meaning. 1 Root "Tzadi-Nun-Nun" means 'to cool down;' the function of this type of flask was to cool down its contents, facilitating their preservation. 2
Gur Aryeh: That is why, out of the hundreds of names of places mentioned in Sefer Yehoshua, the Gemara (Gitin 7a) expounds upon only those names that are doubled - such as "Ad'adah" and "Sansanah" (Yehoshua 15:22,31).
Compare to Yirmeyahu 32:14. (The Torah Temimah (note 52) points out, that the Vilna Gaon's text in the Mechilta is "glassware", rather than "earthenware" - i.e., a utensil that one can see through (Meitzitz).)
