Moshe performed the service . . . [Accordingly,] when it is written here, “He burned the incense of spices upon it” (v. 27), it refers to Moshe, who burnt the incense during the seven days of the Installations before Aharon was anointed. And even on the eighth day, when Aharon began to burn incense, Moshe still burnt the incense [and brought the offerings] except for those which Aharon was commanded specifically for that day. Aharon and his sons brought [only] the offerings that they were commanded specifically for that day.

The daily burnt-offering. This, as opposed to the burnt-offering of Aharon and the burnt-offering of the people, which, on the eighth day, were offered by Aharon — not Moshe — as stated in parshas Shemini.

The mincha of the libations of the tamid . . . [Rashi knows this because] even though there are many [kinds of] meal-offerings, nevertheless since it is written, “And a meal-offering,” without specifying it further, it is speaking of the mincha of the tamid. If it was a mincha that comes separately, it should be mentioned separately, [i.e., by name], since it is not subsidiary to another offering. Perforce, it is speaking of the mincha of the tamid, which is part of the tamid burnt-offering as it says (Bamidbar 28:4—5), “Offer one lamb in the morning . . . and one tenth of an eiphah of fine flour as a meal-offering . . .”

Their encampment is also called מסע . . . Rashi is answering the question: While Yisrael traveled, the cloud did not rest. Rather, B’nei Yisrael encamped only when the cloud rested, and in that place. Why does the verse say, “In all their travels,” implying that the cloud rested even while they traveled? Rashi answers, “Their encampment is also calle מסע .” Accordingly, the verse conveys, “In all their encampments.” It does not mean literally, “In all their travels,” because then the cloud was not upon the mishkon.
