Comentário sobre Números 20:27

ויעש משה AND MOSES DID [AS THE LORD COMMANDED] — Although this thing was hard for him he did not delay to do so (Midrash Tanchuma, Chukat 17).

Although the matter was difficult for him. For if not so, why is it necessary to say “Moshe did…”? Would one have thought that he would transgress the charge of the Omnipresent? Re’m writes: I do not know why Rashi did not make this comment in Parshas Korach where it is written (Bamidbar 17:26) “Moshe did as Hashem commanded Moshe, so he did.” It is possible that he did not comment there because one may say that he did so happily and for his own benefit, so that Bnei Yisroel would not again come to dispute the elevation of the tribe of Levi. There [the happiness due to] the love over his tribe’s elevation was joined with his performance of this commandment, even though he was also doing the command of Hashem. Consequently there Rashi did not wish to make any comment.

In the presence of the entire community. Everyone watched this wondrous event — three gedolei hador ascended the mountain — and no one knew why. They were even more perplexed when they noticed that Aharon wore the priestly vestments, which are prohibited to be worn outside the Mishkan since they are a mixture of wool and linen. They understood that this was a sublime matter based on the word of Hashem, and they watched to see what would come of it.
