Вайикра 8:36 Комментарий: Rashi, Ramban, Rabbeinu Bahya & Tur HaArokh

ויעש אהרן ובניו SO AARON AND HIS SONS DID [ALL THE THINGS] — This is stated to tell their praise — that they did not turn to the right nor to the left (cf. Sifra, Tzav, Mechilta d'Miluim 1 38).

AND AARON AND HIS SONS DID ALL THE THINGS WHICH THE ETERNAL COMMANDED BY THE HAND OF MOSES. Everywhere in this section it says ‘as’ the Eternal commanded Moses,²³¹Above, Verses 13, 17, 21, 29. The Hebrew text here reads: “as the Eternal commanded ‘by the hand of’ Moses.” But this expression I did not find in the Five Books of Moses, but in the Book of Joshua (14:2, etc.). And Ramban’s aim is clearly to distinguish everything that Moses did, which was exactly “as” G-d had commanded him, from that which the sons of Aaron did, as explained in the text. Hence it would seem to be correct that the reading in the text should be “as the Eternal commanded Moses.” It is so also in the Tur who quotes the language of Ramban. but here, since Aaron’s sons added to the command [by bringing strange fire which He had not commanded them],²³²Further, 10:1. He does not say it in this way, since they did not do as the Eternal commanded Moses. Rather, the verse states that they did all the things ‘which’ the Eternal commanded, and they further added to them “the strange fire” of which He said that He had not commanded them.²³²Further, 10:1.

אשר צוה ה' ביד משה, “which G’d had commanded through Moses.” According to Nachmanides the Torah in this instance did not write the usual words כאשר צוה ה' את משה, “just as the Lord had commanded Moses,” as in this instance Aaron’s sons did not do exactly as the Lord had commanded. Rather, they had done “all the things G’d had commanded through Moses,” but they added something, i.e. they introduced alien fire into the Sanctuary” (10,1).
This whole paragraph dealing with the rites of anointing following the appointment of Aaron and his sons as Priests was told the people seven days prior to the Tabernacle being erected, seeing Moses had been commanded to erect the Tabernacle on the twenty-third of Adar. Moses spent the seven days till the first day of Nissan erecting and dismantling the Tabernacle. On the eighth day, G’d called him and commanded him the details of the sacrificial offering legislation, as from that day on the Shechinah had taken up residence in the Tabernacle between the outstretched wings of the cherubs. All the chapters from the beginning of the Book of Leviticus until here were revealed to Moses at that time. The Tabernacle was inaugurated with the seven days of מלואים offerings.
