Comentario citado sobre Números 3:27

NOW THESE ARE THE GENERATIONS OF AARON AND MOSES IN THE DAY THAT THE ETERNAL SPOKE WITH MOSES IN MOUNT SINAI. “And yet [in the following verse] Scripture only enumerates the sons of Aaron, [as it is said, And these are the names of the sons of Aaron! If so, why does it say here and Moses?] They [were indeed the sons of Aaron, but] they are called the generations of Moses because he taught them Torah. This establishes the principle that if one teaches the Torah to one’s fellow man,¹⁴³In our Rashi: “the son of his fellow man.” Scripture accounts it to him as though he had begotten him. In the day that the Eternal spoke to Moses did these children [of Aaron] become his [Moses’], because he taught them then what he learned from the mouth of the Almighty.” This is Rashi’s language.
However, the expression in the day that the Eternal spoke to Moses is intended [not to convey the idea mentioned by Rashi, but] only to say that these were [Aaron’s four] sons [namely, Nadab and Abihu, Eleazar and Ithamar, as mentioned in Verse 2] in the day that the Eternal spoke with Moses in Mount Sinai, and then Scripture states [in the following verses] that Nadab and Abihu died, and that therefore they¹⁴⁴I.e., Aaron and Moses. — Ramban is following the verse which speaks of the children as the generations of Aaron and Moses, for the reason that Rashi explained, but he is of course referring to Aaron’s sons. have no children now except Eleazar and Ithamar. Now Scripture mentions this in order to state that in the day that the Eternal spoke with Moses in Mount Sinai these [sons of Aaron] were chosen to be anointed, and their anointing shall be to them for an everlasting priesthood,¹⁴⁵Exodus 40:15. but as for the rest of the tribe [of Levi], Moses was not commanded that they be chosen [for service in the Tabernacle] until now. And the reason why He mentioned the generations of Aaron and Moses at this place is that since He had completed the census of all Israel by their generations and by their fathers’ houses,⁵⁸Verses 20, 22, etc. and He now wanted to mention the generations of the tribe of Levi, He began with the leaders of that tribe.
According to the plain meaning of Scripture, the sense of [the expression] the generations of Aaron and Moses is that the sons of Aaron were anointed priests separated from [the rest of] the tribe [of Levi] so that they be most holy,¹⁴⁶I Chronicles 23:13. and the generations of Moses were the family of the Amramites which He mentions further on, since of the Amramites there were only the children of Moses,¹⁴⁷Further, Verse 27. Of Amram’s two sons, the sons of the first, Aaron, are already mentioned above; thus the verse must be speaking of Moses’ children only. and they are counted among the Levites. This [verse] is thus similar to that which it is written, The sons of Amram: Aaron and Moses; and Aaron was separated, that he should be sanctified as most holy.¹⁴⁶I Chronicles 23:13. But as for Moses the man of G-d, his sons are named among the tribe of Levi.¹⁴⁸I Chronicles 23:14. And the homiletic interpretation [which Rashi mentioned, that the generations of Aaron are also attributed to Moses because he taught them Torah], the Rabbis based upon [the fact that] Scripture does not state “and these are the names of the sons of Moses,” as it does with the sons of Aaron [stating in Verse 3: These are the names of the sons of Aaron — therefore the Rabbis explained that the verse says: Now these are the generations of Aaron and Moses] to allude to [the principle that] the sons of Aaron are also the generations of Moses because he taught them Torah, for it is the way of the Torah to explain and to allude [to spiritual truths].

לזרח, Rashi comments here that the family of Ohad, had become extinct. He adds that also five of the sons of Binyamin’s family had become extinct. Rashi writes further that what was true of the family of Ohad of the tribe of Reuven, also applied to the family of Etzbon of the tribe of Gad. He explains that that Ozni in verse 16 of our chapter was in fact identical with Etzbon. According to the plain meaning of the text this was because they had not founded a family, i.e. had not married. If you were to ask that if this is correct where was the seventh family of which Rashi wrote that it had become extinct? We might have to assume that the missing family is that of Yishveh of the tribe of Asher. (Compare Genesis46,17, and Numbers 26,44, and the discrepancy in those two verses.) Rashi also writes that four families of the tribe of Levi appear to have disappeared between the first and the second census, i.e. the families of Shiee, Azieli, and some of the family of Yitzhar of whom only the family of Korach is listed here. This is certainly not meant to be an enumeration as only one third of the family are mentioned here when compared to the list in Exodus 6,21. Our author continues to quote lengthy comments by Rashi on this problem. [I have decided that the interested reader will prefer to read the text of Rashi for himself. Ed.]

ונשב בגיא מול בית פעור, “We stayed on in the valley across from Bet-Peor.” We had already been encamped there, as this was the ראש הפסגה Moses had mentioned in verse 27; seeing this was where the people had committed idolatry and adultery. Moses warns them once again concerning the sin of idolatry in the following paragraph.
