Numbers 20:29

ויראו כל העדה AND ALL THE CONGREGATION SAW [THAT AARON HAD DIED] — When they saw Moses and Eleazar descending and that Aaron was not descending with them, they said, “Where, then, is Aaron?” — He replied to them, “He is dead!” They thereupon said, “Is it possible that a man who stood up against the Angel and stayed the plague, — that over him the Angel of Death should have power?!” — Moses at once offered prayer and the ministering angels showed him (Aaron) to them lying upon the bier. They saw and believed (cf. Midrash Tanchuma, Chukat 17). כל בית ישראל [THEY WEPT FOR AARON …] EVEN ALL THE HOUSE OF ISRAEL — all: both men and women, because Aaron used to pursue peace and promoted love between contending parties, and between man and wife (cf. The Fathers According to Rabbi Nathan 12). כי גוע THAT (or because) HE HAD DIED — I say that he who translates these words in the Targum (i.e., anyone who holds that this is the correct rendering) by דהא מית, “because he had died”, is in error unless he also translates in the Targum the word ויראו by ואתחזיאו “they were seen (exposed)”, for our Rabbis stated that this word כי is used here in the sense of “because” only in accordance with a Midrash which relates that the clouds of glory which hitherto enveloped Israel disappeared at Aaron's death, (so that all the congregation were now exposed to the sight of their enemies), and in accordance with what R. Abuhu said (Rosh Hashanah 3a), “Read here not וַיִּרְאוּ but וַיֵּרָאוּ, “they were seen”. It is to this sense of the verb that the meaning of “because” is applicable to the word כי, since that gives the reason for what precedes it: Why were they seen? Because, behold, Aaron had died, and the clouds disappeared. But to the translation in the Targum, וחזו כל כנשתא (“and all the congregation saw”), the meaning of “because” (for the word כי) is not applicable, but only the meaning אשר, “that”, which is one of the usages of the word אי (the Aramaic equivalent of אם, which itself is one of the four classifications of the usage of כי; see ibid). For we find אם used in the sense of אשר “that”, as e.g., (Job 21:4) “so that (ואם) why should I not be impatient?” And many passages where אם occurs may be explained in this sense, as (Job 14:5), “that (אם) his days are determined”.

וַיִּרְאוּ֙ כׇּל־הָ֣עֵדָ֔ה כִּ֥י גָוַ֖ע אַהֲרֹ֑ן וַיִּבְכּ֤וּ אֶֽת־אַהֲרֹן֙ שְׁלֹשִׁ֣ים י֔וֹם כֹּ֖ל בֵּ֥ית יִשְׂרָאֵֽל׃ {ס}        

And when all the congregation saw that Aharon was dead, they mourned for Aharon, thirty days, all the house of Yisra᾽el.
