Rebellious Motivation

In what ways are you defined by what you are against as opposed to a vision of what you stand for?

How do we discern someone's intentions?

(א) וַיִּקַּ֣ח קֹ֔רַח בֶּן־יִצְהָ֥ר בֶּן־קְהָ֖ת בֶּן־לֵוִ֑י וְדָתָ֨ן וַאֲבִירָ֜ם בְּנֵ֧י אֱלִיאָ֛ב וְא֥וֹן בֶּן־פֶּ֖לֶת בְּנֵ֥י רְאוּבֵֽן׃ (ב) וַיָּקֻ֙מוּ֙ לִפְנֵ֣י מֹשֶׁ֔ה וַאֲנָשִׁ֥ים מִבְּנֵֽי־יִשְׂרָאֵ֖ל חֲמִשִּׁ֣ים וּמָאתָ֑יִם נְשִׂיאֵ֥י עֵדָ֛ה קְרִאֵ֥י מוֹעֵ֖ד אַנְשֵׁי־שֵֽׁם׃

(1) Now Korah, son of Izhar son of Kohath son of Levi, betook himself, along with Dathan and Abiram sons of Eliab, and On son of Peleth—descendants of Reuben— (2) to rise up against Moses, together with two hundred and fifty Israelites, chieftains of the community, chosen in the assembly, men of repute.

(ג) וַיִּֽקָּהֲל֞וּ עַל־מֹשֶׁ֣ה וְעַֽל־אַהֲרֹ֗ן וַיֹּאמְר֣וּ אֲלֵהֶם֮ רַב־לָכֶם֒ כִּ֤י כׇל־הָֽעֵדָה֙ כֻּלָּ֣ם קְדֹשִׁ֔ים וּבְתוֹכָ֖ם יְהֹוָ֑ה וּמַדּ֥וּעַ תִּֽתְנַשְּׂא֖וּ עַל־קְהַ֥ל יְהֹוָֽה׃ (ד) וַיִּשְׁמַ֣ע מֹשֶׁ֔ה וַיִּפֹּ֖ל עַל־פָּנָֽיו׃

(3) They combined against Moses and Aaron and said to them, “You have gone too far! For all the community are holy, all of them, and the LORD is in their midst. Why then do you raise yourselves above the LORD’s congregation?” (4) When Moses heard this, he fell on his face.

(ה) וַיְדַבֵּ֨ר אֶל־קֹ֜רַח וְאֶֽל־כׇּל־עֲדָתוֹ֮ לֵאמֹר֒ בֹּ֠קֶר וְיֹדַ֨ע יְהֹוָ֧ה אֶת־אֲשֶׁר־ל֛וֹ וְאֶת־הַקָּד֖וֹשׁ וְהִקְרִ֣יב אֵלָ֑יו וְאֵ֛ת אֲשֶׁ֥ר יִבְחַר־בּ֖וֹ יַקְרִ֥יב אֵלָֽיו׃ (ו) זֹ֖את עֲשׂ֑וּ קְחוּ־לָכֶ֣ם מַחְתּ֔וֹת קֹ֖רַח וְכׇל־עֲדָתֽוֹ׃ (ז) וּתְנ֣וּ בָהֵ֣ן ׀ אֵ֡שׁ וְשִׂ֩ימוּ֩ עֲלֵיהֶ֨ן ׀ קְטֹ֜רֶת לִפְנֵ֤י יְהֹוָה֙ מָחָ֔ר וְהָיָ֗ה הָאִ֛ישׁ אֲשֶׁר־יִבְחַ֥ר יְהֹוָ֖ה ה֣וּא הַקָּד֑וֹשׁ רַב־לָכֶ֖ם בְּנֵ֥י לֵוִֽי׃ (ח) וַיֹּ֥אמֶר מֹשֶׁ֖ה אֶל־קֹ֑רַח שִׁמְעוּ־נָ֖א בְּנֵ֥י לֵוִֽי׃ (ט) הַמְעַ֣ט מִכֶּ֗ם כִּֽי־הִבְדִּיל֩ אֱלֹהֵ֨י יִשְׂרָאֵ֤ל אֶתְכֶם֙ מֵעֲדַ֣ת יִשְׂרָאֵ֔ל לְהַקְרִ֥יב אֶתְכֶ֖ם אֵלָ֑יו לַעֲבֹ֗ד אֶת־עֲבֹדַת֙ מִשְׁכַּ֣ן יְהֹוָ֔ה וְלַעֲמֹ֛ד לִפְנֵ֥י הָעֵדָ֖ה לְשָׁרְתָֽם׃ (י) וַיַּקְרֵב֙ אֹֽתְךָ֔ וְאֶת־כׇּל־אַחֶ֥יךָ בְנֵי־לֵוִ֖י אִתָּ֑ךְ וּבִקַּשְׁתֶּ֖ם גַּם־כְּהֻנָּֽה׃ (יא) לָכֵ֗ן אַתָּה֙ וְכׇל־עֲדָ֣תְךָ֔ הַנֹּעָדִ֖ים עַל־יְהֹוָ֑ה וְאַהֲרֹ֣ן מַה־ה֔וּא כִּ֥י (תלונו) [תַלִּ֖ינוּ] עָלָֽיו׃
(5) Then he spoke to Korah and all his company, saying, “Come morning, the LORD will make known who is His and who is holy, and will grant him access to Himself; He will grant access to the one He has chosen. (6) Do this: You, Korah and all your band, take fire pans, (7) and tomorrow put fire in them and lay incense on them before the LORD. Then the man whom the LORD chooses, he shall be the holy one. You have gone too far, sons of Levi!” (8) Moses said further to Korah, “Hear me, sons of Levi. (9) Is it not enough for you that the God of Israel has set you apart from the community of Israel and given you access to Him, to perform the duties of the LORD’s Tabernacle and to minister to the community and serve them? (10) Now that He has advanced you and all your fellow Levites with you, do you seek the priesthood too? (11) Truly, it is against the LORD that you and all your company have banded together. For who is Aaron that you should rail against him?”
(יב) וַיִּשְׁלַ֣ח מֹשֶׁ֔ה לִקְרֹ֛א לְדָתָ֥ן וְלַאֲבִירָ֖ם בְּנֵ֣י אֱלִיאָ֑ב וַיֹּאמְר֖וּ לֹ֥א נַעֲלֶֽה׃ (יג) הַמְעַ֗ט כִּ֤י הֶֽעֱלִיתָ֙נוּ֙ מֵאֶ֨רֶץ זָבַ֤ת חָלָב֙ וּדְבַ֔שׁ לַהֲמִיתֵ֖נוּ בַּמִּדְבָּ֑ר כִּֽי־תִשְׂתָּרֵ֥ר עָלֵ֖ינוּ גַּם־הִשְׂתָּרֵֽר׃ (יד) אַ֡ף לֹ֣א אֶל־אֶ֩רֶץ֩ זָבַ֨ת חָלָ֤ב וּדְבַשׁ֙ הֲבִ֣יאֹתָ֔נוּ וַתִּ֨תֶּן־לָ֔נוּ נַחֲלַ֖ת שָׂדֶ֣ה וָכָ֑רֶם הַעֵינֵ֞י הָאֲנָשִׁ֥ים הָהֵ֛ם תְּנַקֵּ֖ר לֹ֥א נַעֲלֶֽה׃ (טו) וַיִּ֤חַר לְמֹשֶׁה֙ מְאֹ֔ד וַיֹּ֙אמֶר֙ אֶל־יְהֹוָ֔ה אַל־תֵּ֖פֶן אֶל־מִנְחָתָ֑ם לֹ֠א חֲמ֨וֹר אֶחָ֤ד מֵהֶם֙ נָשָׂ֔אתִי וְלֹ֥א הֲרֵעֹ֖תִי אֶת־אַחַ֥ד מֵהֶֽם׃ (טז) וַיֹּ֤אמֶר מֹשֶׁה֙ אֶל־קֹ֔רַח אַתָּה֙ וְכׇל־עֲדָ֣תְךָ֔ הֱי֖וּ לִפְנֵ֣י יְהֹוָ֑ה אַתָּ֥ה וָהֵ֛ם וְאַהֲרֹ֖ן מָחָֽר׃ (יז) וּקְח֣וּ ׀ אִ֣ישׁ מַחְתָּת֗וֹ וּנְתַתֶּ֤ם עֲלֵיהֶם֙ קְטֹ֔רֶת וְהִקְרַבְתֶּ֞ם לִפְנֵ֤י יְהֹוָה֙ אִ֣ישׁ מַחְתָּת֔וֹ חֲמִשִּׁ֥ים וּמָאתַ֖יִם מַחְתֹּ֑ת וְאַתָּ֥ה וְאַהֲרֹ֖ן אִ֥ישׁ מַחְתָּתֽוֹ׃ (יח) וַיִּקְח֞וּ אִ֣ישׁ מַחְתָּת֗וֹ וַיִּתְּנ֤וּ עֲלֵיהֶם֙ אֵ֔שׁ וַיָּשִׂ֥ימוּ עֲלֵיהֶ֖ם קְטֹ֑רֶת וַֽיַּעַמְד֗וּ פֶּ֛תַח אֹ֥הֶל מוֹעֵ֖ד וּמֹשֶׁ֥ה וְאַהֲרֹֽן׃
(12) Moses sent for Dathan and Abiram, sons of Eliab; but they said, “We will not come! (13) Is it not enough that you brought us from a land flowing with milk and honey to have us die in the wilderness, that you would also lord it over us? (14) Even if you had brought us to a land flowing with milk and honey, and given us possession of fields and vineyards, should you gouge out those men’s eyes? We will not come!” (15) Moses was much aggrieved and he said to the LORD, “Pay no regard to their oblation. I have not taken the ass of any one of them, nor have I wronged any one of them.” (16) And Moses said to Korah, “Tomorrow, you and all your company appear before the LORD, you and they and Aaron. (17) Each of you take his fire pan and lay incense on it, and each of you bring his fire pan before the LORD, two hundred and fifty fire pans; you and Aaron also [bring] your fire pans.” (18) Each of them took his fire pan, put fire in it, laid incense on it, and took his place at the entrance of the Tent of Meeting, as did Moses and Aaron.
(יט) וַיַּקְהֵ֨ל עֲלֵיהֶ֥ם קֹ֙רַח֙ אֶת־כׇּל־הָ֣עֵדָ֔ה אֶל־פֶּ֖תַח אֹ֣הֶל מוֹעֵ֑ד וַיֵּרָ֥א כְבוֹד־יְהֹוָ֖ה אֶל־כׇּל־הָעֵדָֽה׃ {ס} (כ) וַיְדַבֵּ֣ר יְהֹוָ֔ה אֶל־מֹשֶׁ֥ה וְאֶֽל־אַהֲרֹ֖ן לֵאמֹֽר׃ (כא) הִבָּ֣דְל֔וּ מִתּ֖וֹךְ הָעֵדָ֣ה הַזֹּ֑את וַאֲכַלֶּ֥ה אֹתָ֖ם כְּרָֽגַע׃ (כב) וַיִּפְּל֤וּ עַל־פְּנֵיהֶם֙ וַיֹּ֣אמְר֔וּ אֵ֕ל אֱלֹהֵ֥י הָרוּחֹ֖ת לְכׇל־בָּשָׂ֑ר הָאִ֤ישׁ אֶחָד֙ יֶחֱטָ֔א וְעַ֥ל כׇּל־הָעֵדָ֖ה תִּקְצֹֽף׃ {ס} (כג) וַיְדַבֵּ֥ר יְהֹוָ֖ה אֶל־מֹשֶׁ֥ה לֵּאמֹֽר׃ (כד) דַּבֵּ֥ר אֶל־הָעֵדָ֖ה לֵאמֹ֑ר הֵֽעָלוּ֙ מִסָּבִ֔יב לְמִשְׁכַּן־קֹ֖רַח דָּתָ֥ן וַאֲבִירָֽם׃ (כה) וַיָּ֣קׇם מֹשֶׁ֔ה וַיֵּ֖לֶךְ אֶל־דָּתָ֣ן וַאֲבִירָ֑ם וַיֵּלְכ֥וּ אַחֲרָ֖יו זִקְנֵ֥י יִשְׂרָאֵֽל׃ (כו) וַיְדַבֵּ֨ר אֶל־הָעֵדָ֜ה לֵאמֹ֗ר ס֣וּרוּ נָ֡א מֵעַל֩ אׇהֳלֵ֨י הָאֲנָשִׁ֤ים הָֽרְשָׁעִים֙ הָאֵ֔לֶּה וְאַֽל־תִּגְּע֖וּ בְּכׇל־אֲשֶׁ֣ר לָהֶ֑ם פֶּן־תִּסָּפ֖וּ בְּכׇל־חַטֹּאתָֽם׃
(19) Korah gathered the whole community against them at the entrance of the Tent of Meeting. Then the Presence of the LORD appeared to the whole community, (20) and the LORD spoke to Moses and Aaron, saying, (21) “Stand back from this community that I may annihilate them in an instant!” (22) But they fell on their faces and said, “O God, Source of the breath of all flesh! When one man sins, will You be wrathful with the whole community?” (23) The LORD spoke to Moses, saying, (24) “Speak to the community and say: Withdraw from about the abodes of Korah, Dathan, and Abiram.” (25) Moses rose and went to Dathan and Abiram, the elders of Israel following him. (26) He addressed the community, saying, “Move away from the tents of these wicked men and touch nothing that belongs to them, lest you be wiped out for all their sins.”
(כז) וַיֵּעָל֗וּ מֵעַ֧ל מִשְׁכַּן־קֹ֛רַח דָּתָ֥ן וַאֲבִירָ֖ם מִסָּבִ֑יב וְדָתָ֨ן וַאֲבִירָ֜ם יָצְא֣וּ נִצָּבִ֗ים פֶּ֚תַח אׇֽהֳלֵיהֶ֔ם וּנְשֵׁיהֶ֥ם וּבְנֵיהֶ֖ם וְטַפָּֽם׃ (כח) וַיֹּ֘אמֶר֮ מֹשֶׁה֒ בְּזֹאת֙ תֵּֽדְע֔וּן כִּֽי־יְהֹוָ֣ה שְׁלָחַ֔נִי לַעֲשׂ֕וֹת אֵ֥ת כׇּל־הַֽמַּעֲשִׂ֖ים הָאֵ֑לֶּה כִּי־לֹ֖א מִלִּבִּֽי׃ (כט) אִם־כְּמ֤וֹת כׇּל־הָֽאָדָם֙ יְמֻת֣וּן אֵ֔לֶּה וּפְקֻדַּת֙ כׇּל־הָ֣אָדָ֔ם יִפָּקֵ֖ד עֲלֵיהֶ֑ם לֹ֥א יְהֹוָ֖ה שְׁלָחָֽנִי׃ (ל) וְאִם־בְּרִיאָ֞ה יִבְרָ֣א יְהֹוָ֗ה וּפָצְתָ֨ה הָאֲדָמָ֤ה אֶת־פִּ֙יהָ֙ וּבָלְעָ֤ה אֹתָם֙ וְאֶת־כׇּל־אֲשֶׁ֣ר לָהֶ֔ם וְיָרְד֥וּ חַיִּ֖ים שְׁאֹ֑לָה וִֽידַעְתֶּ֕ם כִּ֧י נִֽאֲצ֛וּ הָאֲנָשִׁ֥ים הָאֵ֖לֶּה אֶת־יְהֹוָֽה׃ (לא) וַיְהִי֙ כְּכַלֹּת֔וֹ לְדַבֵּ֕ר אֵ֥ת כׇּל־הַדְּבָרִ֖ים הָאֵ֑לֶּה וַתִּבָּקַ֥ע הָאֲדָמָ֖ה אֲשֶׁ֥ר תַּחְתֵּיהֶֽם׃ (לב) וַתִּפְתַּ֤ח הָאָ֙רֶץ֙ אֶת־פִּ֔יהָ וַתִּבְלַ֥ע אֹתָ֖ם וְאֶת־בָּתֵּיהֶ֑ם וְאֵ֤ת כׇּל־הָאָדָם֙ אֲשֶׁ֣ר לְקֹ֔רַח וְאֵ֖ת כׇּל־הָרְכֽוּשׁ׃ (לג) וַיֵּ֨רְד֜וּ הֵ֣ם וְכׇל־אֲשֶׁ֥ר לָהֶ֛ם חַיִּ֖ים שְׁאֹ֑לָה וַתְּכַ֤ס עֲלֵיהֶם֙ הָאָ֔רֶץ וַיֹּאבְד֖וּ מִתּ֥וֹךְ הַקָּהָֽל׃
(27) So they withdrew from about the abodes of Korah, Dathan, and Abiram. Now Dathan and Abiram had come out and they stood at the entrance of their tents, with their wives, their children, and their little ones. (28) And Moses said, “By this you shall know that it was the LORD who sent me to do all these things; that they are not of my own devising: (29) if these men die as all men do, if their lot be the common fate of all mankind, it was not the LORD who sent me. (30) But if the LORD brings about something unheard-of, so that the ground opens its mouth and swallows them up with all that belongs to them, and they go down alive into Sheol, you shall know that these men have spurned the LORD.” (31) Scarcely had he finished speaking all these words when the ground under them burst asunder, (32) and the earth opened its mouth and swallowed them up with their households, all Korah’s people and all their possessions. (33) They went down alive into Sheol, with all that belonged to them; the earth closed over them and they vanished from the midst of the congregation.

There has been much grumbling and discontent by B'nai Yisrael directed against Moses. Why not complain to God?

(ח) וַיֹּ֣אמֶר מֹשֶׁ֗ה בְּתֵ֣ת יְהֹוָה֩ לָכֶ֨ם בָּעֶ֜רֶב בָּשָׂ֣ר לֶאֱכֹ֗ל וְלֶ֤חֶם בַּבֹּ֙קֶר֙ לִשְׂבֹּ֔עַ בִּשְׁמֹ֤עַ יְהֹוָה֙ אֶת־תְּלֻנֹּ֣תֵיכֶ֔ם אֲשֶׁר־אַתֶּ֥ם מַלִּינִ֖ם עָלָ֑יו וְנַ֣חְנוּ מָ֔ה לֹא־עָלֵ֥ינוּ תְלֻנֹּתֵיכֶ֖ם כִּ֥י עַל־יְהֹוָֽה׃

(8) Since it is the LORD,” Moses continued, “who will give you flesh to eat in the evening and bread in the morning to the full, because the LORD has heard the grumblings you utter against Him, what is our part? Your grumbling is not against us, but against the LORD!”

וַיֹּֽאמְרוּ֙ אֶל־מֹשֶׁ֔ה דַּבֵּר־אַתָּ֥ה עִמָּ֖נוּ וְנִשְׁמָ֑עָה וְאַל־יְדַבֵּ֥ר עִמָּ֛נוּ אֱלֹהִ֖ים פֶּן־נָמֽוּת׃
“You speak to us,” they said to Moses, “and we will obey; but let not God speak to us, lest we die.”

Holiness

וַיְדַבֵּ֥ר יְהוָ֖ה אֶל־מֹשֶׁ֥ה לֵּאמֹֽר דַּבֵּ֞ר אֶל־כָּל־עֲדַ֧ת בְּנֵי־יִשְׂרָאֵ֛ל וְאָמַרְתָּ֥ אֲלֵהֶ֖ם קְדֹשִׁ֣ים תִּהְי֑וּ כִּ֣י קָד֔וֹשׁ אֲנִ֖י יְהוָ֥ה אֱלֹהֵיכֶֽם׃

The LORD spoke to Moses, saying: Speak to the whole Israelite community and say to them: You shall be holy, for I, the LORD your God, am holy.

וִהְיִ֤יתֶם לִי֙ קְדֹשִׁ֔ים כִּ֥י קָד֖וֹשׁ אֲנִ֣י יְהוָ֑ה וָאַבְדִּ֥ל אֶתְכֶ֛ם מִן־הָֽעַמִּ֖ים לִהְי֥וֹת לִֽי׃
You shall be holy to Me, for I the LORD am holy, and I have set you apart from other peoples to be Mine.

וְהִ֨תְקַדִּשְׁתֶּ֔ם וִהְיִיתֶ֖ם קְדֹשִׁ֑ים כִּ֛י אֲנִ֥י יְהוָ֖ה אֱלֹהֵיכֶֽם׃

You shall sanctify yourselves and be holy, for I the LORD am your God.

(א) רב לכם...די לכם מה שהשתררתם עלינו עד היום, כי עד עתה היינו צריכים לכם, ומעתה שהוקם המשכן אין לנו צורך בכם...

It is too much for you...it is enough for you that you have ruled over us until today. For until now, we needed you, but since the establishment of the mishkan, we don't need you...

לְמַ֣עַן תִּזְכְּר֔וּ וַעֲשִׂיתֶ֖ם אֶת־כָּל־מִצְוֺתָ֑י וִהְיִיתֶ֥ם קְדֹשִׁ֖ים לֵֽאלֹהֵיכֶֽם׃
Thus you shall be reminded to observe all My commandments and to be holy to your God.

Is attaining a state of holiness an automatic? In what way do the texts above provide a roadmap to holiness?

Genuine holiness is the altruistic striving for good for its own sake, not out of self-interest. Rav Kook, Ein Eyah vol. I, p. 104

(יב) אַל־תְּ֭בוֹאֵנִי רֶ֣גֶל גַּאֲוָ֑ה וְיַד־רְ֝שָׁעִ֗ים אַל־תְּנִדֵֽנִי׃

(12) Let not the foot of the arrogant tread on me, or the hand of the wicked drive me away.

Rav Sala said, "Every arrogant person will eventually sin ..."

Rav Nachman said, "It is evident that an arrogant person is one who has already sinned"(Talmud, Taanit 7b). Rav Sala and Rav Nachman disagree. Does being arrogant cause one to sin, or is it the other way around? [Abraham Twerski]

(יז) כָּל מַחֲלֹקֶת שֶׁהִיא לְשֵׁם שָׁמַיִם, סוֹפָהּ לְהִתְקַיֵּם. וְשֶׁאֵינָהּ לְשֵׁם שָׁמַיִם, אֵין סוֹפָהּ לְהִתְקַיֵּם. אֵיזוֹ הִיא מַחֲלֹקֶת שֶׁהִיא לְשֵׁם שָׁמַיִם, זוֹ מַחֲלֹקֶת הִלֵּל וְשַׁמַּאי. וְשֶׁאֵינָהּ לְשֵׁם שָׁמַיִם, זוֹ מַחֲלֹקֶת קֹרַח וְכָל עֲדָתוֹ:

(17) Every dispute that is for the sake of Heaven, will in the end endure; But one that is not for the sake of Heaven, will not endure. Which is the controversy that is for the sake of Heaven? Such was the controversy of Hillel and Shammai. And which is the controversy that is not for the sake of Heaven? Such was the controversy of Korah and all his congregation.

(ג) וְהָאִ֥ישׁ מֹשֶׁ֖ה עָנָ֣ו מְאֹ֑ד מִכֹּל֙ הָֽאָדָ֔ם אֲשֶׁ֖ר עַל־פְּנֵ֥י הָאֲדָמָֽה׃ {ס}

(3) Now Moses was a very humble man, more so than any other man on earth.

(במדבר טז, כה) ויקם משה וילך אל דתן ואבירם אמר ר"ל מכאן שאין מחזיקין במחלוקת דאמר רב כל המחזיק במחלוקת עובר בלאו שנאמר (במדבר יז, ה) ולא יהיה כקרח וכעדתו

With regard to the verse: “And Moses arose and went to Dathan and Abiram” (Numbers 16:25), Reish Lakish says: From here we derive that one may not perpetuate a dispute, as Rav says: Anyone who perpetuates a dispute violates a prohibition, as it is stated: “And he will not be like Korah and his assembly, as the Lord spoke by the hand of Moses to him” (Numbers 17:5). Even the aggrieved party must seek to end the dispute. Dathan and Abiram accused Moses and by right should have initiated the reconciliation. Nevertheless, Moses was not insistent on this; he went to them.

The greatest leader is therefore the most humble. The name given to this is servant leadership, and its origin is in the Torah. The highest accolade given to Moses is that he was “the servant of the Lord” (Deut. 34:5). Moses is given this title eighteen times in Tanach. Only one other leader merits the same description: Joshua, who is described this way twice. Rabbi Lord Jonathan Sacks

Mussar...

Whenever you notice a fault in other people, check where you yourself have that fault.

We have a strong tendency to notice our own faults in others (see Kidushin 70b). This provides us with many opportunities to learn about our own shortcomings, since it is easier to see a fault in someone else than in ourselves. ~ R' Chaim of Volozhin zt"l

Women's role in this parsha through Midrash: [via Jewish Women's Archive]

This explains his name: “On,” because he sat in lamentation (be-onenut) for having participated in the rebellion against Moses and Aaron; “Peleth,” because wonders (pela’ot) were performed for him and he was saved from death by virtue of his wife. The Rabbis apply to this woman the first part of Prov. 14:1: “The wisest of women builds her house,” for she saved her household with her wisdom. This is contrasted with the second part of the verse—“but folly tears it down with its own hands”—which the Rabbis use to depict the wife of Korah, since the latter was responsible for the downfall of her house (BT Sanhedrin 109b–110a; Tanhuma [ed. Buber], Korah 24).

כָּל מַחֲלֹקֶת שֶׁהִיא לְשֵׁם שָׁמַיִם, סוֹפָהּ לְהִתְקַיֵּם. וְשֶׁאֵינָהּ לְשֵׁם שָׁמַיִם, אֵין סוֹפָהּ לְהִתְקַיֵּם. אֵיזוֹ הִיא מַחֲלֹקֶת שֶׁהִיא לְשֵׁם שָׁמַיִם, זוֹ מַחֲלֹקֶת הִלֵּל וְשַׁמַּאי. וְשֶׁאֵינָהּ לְשֵׁם שָׁמַיִם, זוֹ מַחֲלֹקֶת קֹרַח וְכָל עֲדָתוֹ:
Every dispute that is for the sake of Heaven, will in the end endure; But one that is not for the sake of Heaven, will not endure. Which is the controversy that is for the sake of Heaven? Such was the controversy of Hillel and Shammai. And which is the controversy that is not for the sake of Heaven? Such was the controversy of Korah and all his congregation.

The consequences of jealousy....

You shall not covet your neighbor’s house: you shall not covet your neighbor’s wife, or his male or female slave, or his ox or his ass, or anything that is your neighbor’s.

הרי קרח מצד הקנאה נתלבש בגאוה, על כן רצה קרח להתגדל עליו, וזהו (במדבר טז, א) ויקח קרח בן יצהר כו' לקח בדעתו כי הוא בן יצהר. ובמדרש רבה (יח, טז) א"ר לוי למה חלק על משה, אמר אני בן יצהר והוא שמן כמ"ש (דברים יד, כג) תירושך ויצהריך, והשמן צף למעלה. אח"כ לקח בדעתו כי הוא בן קהת המיוחס לנשיאת הארון הקודש. גם חשב כי הוא בן יצהר וא"כ לו היה ראוי הנשיאות, ולא לאליצפן בן עוזיאל שהוא אח הרביעי, כל אלו הגאיות נתלבש בהם מצד הקנאה והיא הוציאה אותו מן העולם:
Jealousy caused Korach to "robe himself" in haughtiness, caused him to aspire to greatness. This is why the expression ויקח קרח, should be understood as "he took the fact that he was the son of Yitzhar into consideration, and decided he was entitled to higher rank than had been accorded him so far. We know that Bamidbar Rabbah quotes Rabbi Levi as saying that Korach considered the fact that he was the son of יצהר, [another name for oil], and that oil always floats on top. Furthermore, he considered the fact that he was also the grandson of Kehat who had been found worthy to found the family that would carry the Holy Ark. By dwelling on these points he convinced himself that the position of leadership of the Kehatites should have belonged to him, and not to Elitzafan who was only fourth in line. These were the considerations which resulted in his being deprived of his life and his future.
דתן ואבירם כו' לקחו במחשבותם שהם בני ראובן הבכור והם ראוים לגדולה, על כן שפטו משפט מעוקל וכפרו בנבואת משה הפרטית, דהיינו ההתמנות, וחטאם היה בהתאוה שמוציא את האדם מהעולם והיא בהפך ממעלת איזה עשיר כו'. וחשבו על משה רבינו ע"ה שעשה זה להעשיר את משפחתו, על כן עשה לאהרן ובניו כהנים ושבטו לוים שיתעשרו במתנות כהונה ובמעשרות כו'. גם הקטורת מעשרת, כמו שאמרו רז"ל (יומא כו, א). וזהו שהתרעמו (במדבר טז, יד) ותתן לנו נחלת שדה וכרם וכו'. וזהו יצאו נצבים פתח אהליהם, נצבים ולא זכרו בסוד המזוזה המורה על שלימות הממון כמו שכתבתי לעיל (ד"ה ועל אלה). וכבר כתבתי לעיל (ד"ה על דרך הפשט), כי ג' אלה קנאה תאוה וכבוד לעומתם גבור עשיר וחכם, והם ג' שלמויות גוף ממון נפש, והם ג' תיקונים ציצית מזוזה תפילין. וקרח שלבש בקנאה, התלוצץ בציצית. ודתן ואבירם שנתלבשו בתאוה, לא שמו עיניהם על המזוזה. וענין ר"ן איש, היה עניינם בסוד תפילין כמו שנפרש אי"ה:

What were Datan and Aviram's considerations? They first considered that as descendants of Reuben, the firstborn amongst the tribes, they were entitled to high positions. As a result they perverted justice by denying that Moses was a prophet, i.e. his having been appointed as leader rightfully. Their sin was the greed which causes a person to lose his life in this world and the World to Come, the exact reverse of the recipe for riches: counting one's blessings, as we have learned from Ben Zoma in Avot. They had thought that Moses had secured his leadership position only to enrich himself and his family, that he appointed Aaron and his sons Priests and the members of his tribe as Levites only so they could live off the various gifts that the Israelites had to hand over to them. They also thought that they had wanted to monopolize these positions since the bringing of incense enriches those who offer it (Yuma 26). This is why they complained saying: "did you give us the inheritance of field or vineyard" (16,14)? This is the meaning of: "they assumed an upright position at the entrance of their tent, etc." (16,27). They failed to remember that the mezuzah's metaphysical dimension is sufficient to assure financial security, as pointed out earlier. I have already outlined that the three negative virtues of jealousy, greed, and the pursuit of personal honour, correspond to the problems associated with power, wealth, and wisdom respectively. The three areas in which man has to achieve a degree of perfection are his body, his financial resources, and his spiritual resources (his soul). The three commandments which provide help in achieving these perfections are ציצית, מזוזה, and תפילין.

One way the Talmud responds to 'eternal punishment'....

ת"ר עדת קרח אין להם חלק לעולם הבא שנאמר ותכס עליהם הארץ בעולם הזה ויאבדו מתוך הקהל לעולם הבא דברי רבי עקיבא רבי יהודה בן בתירא אומר הרי הן כאבידה המתבקשת שנאמר (תהלים קיט, קעו) תעיתי כשה אובד בקש עבדך כי מצותיך לא שכחתי:

The Sages taught in a baraita (Tosefta 13:9): The members of the assembly of Korah have no share in the World-to-Come, as it is stated: “And the earth closed upon them” (Numbers 16:33), meaning in this world, and also: “And they perished from among the assembly” (Numbers 16:33), meaning in the World-to-Come; this is the statement of Rabbi Akiva. Rabbi Yehuda ben Beteira says: Although it says that they perished, they are like a lost item that is sought, ultimately found, and rehabilitated, as it is stated: “I have gone astray like a lost sheep; seek out your servant, for I do not forget your mitzvot” (Psalms 119:176).
