NUM251 (Continued from [[LEV585]] Leviticus 19:17 rebuke WAGS 74-5). Rambam is of the opinion that this was Moshe Rabbeinu's sin at the mei merivah--he addressed the Jewish people in an angry manner, as the verse says, "Listen, rebellious ones…" [this verse]. Rambam explains that the simplest Jew of Moshe Rabbeinu's generation reached the same level of spiritual awareness as Yechezkel Ben Buzi the prophet. Thus, it was wrong of Moshe to express anger to people of such stature. Furthermore, the Jewish people understandably concluded that Moshe's anger was a manifestation of Hashem's anger toward them; in actuality, Hashem was not angry with them. Thus, in a certain sense, Moshe Rabbeinu was guilty of desecrating the name of Hashem.
