Nombres 20:29

The entire community saw. When they saw Moshe and Elozor descending, and Aharon did not desend, they said,”Where is Aharon”? He said to them, “He died.” They said, “Can it be that someone who stood up to the angel and stopped the plague is under the dominion of the angel of death”? Moshe immediately begged for mercy, and the ministering angels showed him to them, lying in the bed. They saw, and believed.

The entire house of Yisroel. Men and women, because Aharon pursued peace, and instilled affection between antagonists, and between husband and wife.

That [Aharon] died. I say that anyone who translates [כִּי גָוַע as] דְּהָא מִית (“because [Aharon] died”), is mistaken, unless he also translates וַיִּרְאוּ as וְאִתְחֲזִיאוּ ([The community] “was exposed”). Since the Rabbis’ comment, that כִּי here is understood as “because,” is valid only according to the Midrashic comment that the clouds of glory departed, as R’ Abohu said, “do not read וַיִּרְאוּ (‘they [the community] saw,’), but וַיֵּרָאוּ, (‘they [the community] were exposed’).” According to this interpretation, דְּהָא (“because”), is the proper usage, since it clarifies what precedes it. Why were they exposed? Because Aharon died. However, according to Targum [Onkelos who translates] “the entire community saw,” “because” is not the proper usage, but “that,” from the אִי meaning, as we find אִם meaning “that.” As in, “that [I ask], why shouldn’t I be distressed”?Sf? and many clear usages in this sense, [like] “that his days are designated.”

And when the soul of Aharon was at rest, the Cloud of Glory was lifted up on the first day of the month Ab; and all the congregation beheld Mosheh come down from the mountain with rent garments; and he wept and said, Woe unto me, for thee, my brother Aharon, the pillar of Israel's prayers! And they too wept for Aharon thirty days, the men and the women of Israel.
