Commentaire sur Les Nombres 28:6

העשיה בהר סיני WHICH WAS OFFERED BY MOUNT SINAI — i.e., like those continual burnt offerings which were offered during the days of the installation ceremony (which took place whilst the people were encamped by Mount Sinai). — Another explanation of העשיה בהר סיני is: It compares the continual burnt offering to the burnt offering of Mount Sinai — to that which was offered on the fifth day of the third month, before the Giving of the Torah (see Rashi on Exodus 19:11), of which it is written, (Exodus 24:6) “And he put it (the blood) in basins”: this teaches, therefore, that it (the continual burnt-offering) requires a vessel for the reception of the blood (Sifra, Tzav, Chapter 18 8).

עולת תמיד העשויה בהר סיני, before the sin of the golden calf when there was not yet a need to accompany this sacrifice with libations.

העשויה בהר סיני, “which was instituted at Mount Sinai.” This is a reference to the offerings brought daily during the inaugural procedures of the Tabernacle (Exodus 29). This was a period prior to the attribute of כבוד moving from the top of the mountain to the top of the Tabernacle. The wording here seems to suggest that after their stay around Mount Sinai the Israelites did not continue to offer these burnt-offerings in the desert at all. In Chagigah 6 Rabbi Eleazar understands the words עולת תמיד העשויה בהר סיני as meaning that the relevant procedures were taught at Mount Sinai whereas the offerings were not offered there at all. Rabbi Akiva, however, understood the verse to mean that this procedure was first introduced at Mount Sinai. [Presumably prior to the building of the Tabernacle, as the Tabernacle was not built till nine months after the sin of the golden calf. A better explanation is that of Tosafot that the disqualification of the Israelites was the sin of the spies. This leaves other problems. Ed.] and never again interrupted. This poses the problem of a verse in Amos 5,25: “the meat-offerings and gift-offerings which you offered to Me during the forty years in the desert.” Why did the prophet not mention the burnt-offerings offered during that period? The answer given is that during those 40 years the daily-burnt-offering represented only the tribe of Levi who had not been guilty of the sin of the golden calf and who therefore were not out of grace. This teaches that even according to the view of Rabbi Akiva who holds that once introduced this procedure was not abandoned even temporarily, the meaning of the offering was different.
