Commentaire sur Les Nombres 4:36

אלפים שבע מאות וחמשים, two thousand seven hundred and fifty. Here, when reporting the number of Kehatites the Torah did not write: "and seven hundred," i.e. ושבע מאות, as it did when reporting the number of the clan of Gershon between thirty and fifty in verse 40. Also, when reporting the number of Merarites in verse 44 the "hundreds" are preceded by the conjunctive letter ו i.e. ומאתים. Perhaps the absence of the letter ו when reporting the number of Kehatites is an allusion to Korach and those who died with him seeing they belonged to the clan of Kehat. Alternatively, the number seven hundred was subject to correction shortly after the time of the count as the uprising of Korach occurred either immediately before the debacle with the spies or shortly thereafter, at any rate during the same summer. While it is true that the Torah mentioned only one Kehatite by name during that uprising, i.e. Korach himself, other relatives may have been inclined to join him; at least they shared part of his guilt by not protesting Korach's conduct.
