ציטירנדיקער פּירוש אויף במדבר 20:2

עין משפט, according to Rashi, the name mentioned here is borrowed from the name of that place in later years. At that time Moses and Aaron would be judged in that location. (מי מריבה). Nachmanides expresses his confusion about this commentary, referring to the קדש, which, he claims is identical with קדש ברנע that we know from Numbers 20,2 in the desert of Tzin, where Moses and Aaron failed to speak to the rock. [I will not bother to translate all he writes as it is clearly based on a misunderstanding of the location. Joshua 12,22 as well as 20,7 refers to locations known as Kedesh in the land of Canaan, There were numerous locations known by that name, so that there is nothing strange about Rash’s explanation, though his apparent conclusion that this was the location later on known as מי מריבה is geographically untenable.

Listen, you rebels! Some of the Sages held the view that Moshe and Aharon’s sin was that they slighted Bnei Yisroel’s honor; they slighted the honor of people who had not sinned. The verse only informs us of the sin of the עם (the people) — a reference to the coarse ones among them, known as the mixed multitude. However, “the community” is the community of the righteous among Yisroel, called “the congregation of Adonoy,” and they had not spoken at all in this matter. They only assembled, and perhaps this was for the sake of requesting Moshe and Aharon to make efforts in prayer in order to satiate their thirst. They did not sin at all, and yet Moshe spoke harshly to them and called them rebels.
