Why does the Torah juxtapose the Parshah of Korach next to that of Tzitzis?
Rashi: Because Korach dressed his men in cloaks that were made entirely of Techeiles, stood them before Moshe and asked him whether they were Chayav Tzitzis. 1 When he answered in the affirmative, they began to mock him
What did Korach take?
Rashi #1 (citing Targum Onkelos and the Midrash Tanchuma): He took himself to one side 1
See Ramban's objection to Rashi's interpretation of the Midrash.
See Pasuk 3.
As stated in the next Pasuk.
Why does the Torah stop at Levi? Why does it not go back to Ya'akov?
How did Dasan and Aviram become associated with Korach?
Rashi: They became associated with Korach because the tribe of Re'uven, to which they belonged, encamped in the south, next to K'has, to which Korach belonged. 1
Rashi: 'Woe to the Rasha, Woe to his neighbor!'
To whom does "B'nei Re'uven" pertain?
Rashi: "B'nei Re'uven" pertains to Dasan, Aviram and On ben Peles.
Why is On ben Peles not mentioned again after this Pasuk?
Da'as Zekeinim mi'Ba'alei Tosfos (citing Sanhedrin, 109b): Who convinced him as a Talmid of Korach than as a Talmid of Moshe; then, with his consent, she gave him strong wine and put him to sleep, and, when Korach's men came to fetch him, she frightened them off by sitting outside her tent combing her hair. The Da'as Zekeinim mi'Ba'alei Tosfos also cites a Midrash that also attributes Korach's rebellion to his wicked wife, who urged him to challenge Moshe, for publicly embarrassing him together with all the Levi'im, when he ordered them to be completely shaven, bald and waved like a Lulav, by Aharon (See Bamidbar 8:7 & 11). And it is to these two women to whom the Pasuk in Mishlei, 14:1) refers when it writes "Chochmas Nashim Bansah Beisah (the wife of On), ve'Aveles be'Yadehah Teharsenah" (the wife of Korach).
Ramban: Wich explains why he was neither swallowed up with Dasan and Aviram nor burned with the two hundred and fifty men.
What sparked off Korach's rebellion?
Rashi and Ramban (citing Midrash Tanchuma): His jealousy of his younger cousin, Elitzafan ben Uzi'el, 1 who had been appointed the Nasi of K'has, in spite of the fact that he was the son of Yitz'har (Korach's father)'s younger brother, Uziel, 2 (and because he was jealous of Aharon's appointment to the Kehunah Gedolah
Rashi (on Pasuk 3): Although it was his jealousy that sparked off the rebellion, he attacked Moshe on his appointment of Aharon as Kohen Gadol, which he also coveted.
See Shemos 6:18. If the sons of K'has' oldest son Amram, took the kingship and the Kehunah Gedolah, then it is he, the son of his second son, Yitzhar, who ought to have taken the next important position, and Moshe had no right to appoint the son of K'has' youngest son.
Ramban: As Moshe specifically stated in Pasuk 10.
When did the episode of Korach take place?
Ramban #2: It took place in Kadeish Barne'a in Midbar Paran, after the episode of the spies, when the atmosphere in the camp was conducive to rebellion. 3
Ramban: Based on the principle 'Ein Mukdam u'Me'uchar ba'Torah'. The Ramban objects to this explanation however, because the Torah always follows the chronological order, unless there is good reason not to.
Ramban #1 (citing Ibn Ezra): And the people thought that Moshe distributed the important positions to his tribe and to his relatives.
Ramban: Since it took place immediately after the multiple punishments (Tav'eirah, Kivros ha'Ta'avah and the Meraglim), and the people were dejected. Moreover, in Midbar Sinai, Moshe was still extremely popular, since, in spite of their sins, he had, via his Tefilos, succeeded in staving off the punishments, as opposed to here, where he had ended up decreeing that they would die in the desert. See Ramban, end of the Pasuk..
Why did the B'nei Levi and Dasan and Aviram join the rebellion?
Ramban #2 (citing the Ibn Ezra): The B'nei Levi, 4 because they accused Moshe of appointing them to secondary positions to serve the Kohanim, 5 and Dasan and Aviram, of taking away the Bechorah from their father Re'uven and handing it to Yosef. 6
Ramban #3: Dasan and Aviram turned on Moshe because, as they specifically stated, they accused Moshe of taking them into desert in order to kill them. 7
Ramban: Although in fact, it was Ya'akov who made the switch.
See Pasuk 7 & 8.
Ramban (citing the Ibn Ezra): Whereas the people accused him of choosing his brother as Kohen Gadol, the B'nei K'has, his relatives, for the choicest Avodah, and the Levi
