The Sons of Korach
(א) וַיְהִ֖י אַחֲרֵ֣י הַמַּגֵּפָ֑ה (פ) וַיֹּ֤אמֶר יְהוָה֙ אֶל־מֹשֶׁ֔ה וְאֶ֧ל אֶלְעָזָ֛ר בֶּן־אַהֲרֹ֥ן הַכֹּהֵ֖ן לֵאמֹֽר׃
(1) When the plague was over, the LORD said to Moses and to Eleazar son of Aaron the priest,
(ב) שְׂא֞וּ אֶת־רֹ֣אשׁ ׀ כָּל־עֲדַ֣ת בְּנֵי־יִשְׂרָאֵ֗ל מִבֶּ֨ן עֶשְׂרִ֥ים שָׁנָ֛ה וָמַ֖עְלָה לְבֵ֣ית אֲבֹתָ֑ם כָּל־יֹצֵ֥א צָבָ֖א בְּיִשְׂרָאֵֽל׃
(2) “Take a census of the whole Israelite community from the age of twenty years up, by their ancestral houses, all Israelites able to bear arms.”
(ט) וּבְנֵ֣י אֱלִיאָ֔ב נְמוּאֵ֖ל וְדָתָ֣ן וַאֲבִירָ֑ם הֽוּא־דָתָ֨ן וַאֲבִירָ֜ם קרואי [קְרִיאֵ֣י] הָעֵדָ֗ה אֲשֶׁ֨ר הִצּ֜וּ עַל־מֹשֶׁ֤ה וְעַֽל־אַהֲרֹן֙ בַּעֲדַת־קֹ֔רַח בְּהַצֹּתָ֖ם עַל־יְהוָֽה׃
(9) The sons of Eliab were Nemuel, and Dathan and Abiram. These are the same Dathan and Abiram, chosen in the assembly, who agitated against Moses and Aaron as part of Korah’s band when they agitated against the LORD.

(י) וַתִּפְתַּ֨ח הָאָ֜רֶץ אֶת־פִּ֗יהָ וַתִּבְלַ֥ע אֹתָ֛ם וְאֶת־קֹ֖רַח בְּמ֣וֹת הָעֵדָ֑ה בַּאֲכֹ֣ל הָאֵ֗שׁ אֵ֣ת חֲמִשִּׁ֤ים וּמָאתַ֙יִם֙ אִ֔ישׁ וַיִּהְי֖וּ לְנֵֽס׃

(10) Whereupon the earth opened its mouth and swallowed them up with Korah—when that band died, when the fire consumed the two hundred and fifty men—and they became an example.

(יא) וּבְנֵי־קֹ֖רַח לֹא־מֵֽתוּ׃ (ס)

(11) The sons of Korah, however, did not die.

(במדבר כו, יא) ובני קרח לא מתו תנא משום רבינו אמרו מקום נתבצר להם בגיהנם וישבו עליו ואמרו שירה אמר רבה בר בר חנה זימנא חדא הוה קאזלינא באורחא אמר לי ההוא טייעא תא ואחוי לך בלועי דקרח אזיל חזא תרי בזעי דהוה קא נפק קיטרא מנייהו שקל גבבא דעמרא אמשיי' מיא ואותביה בריש רומחיה ואחלפי' התם איחרך א"ל אצית מה שמעת ושמעית דהוו קאמרי הכי משה ותורתו אמת והן בדאים

With regard to the verse: “And the sons of Korah did not die” (Numbers 26:11), it is taught in a baraita that in the name of our teacher, the Sages said: A place was fortified for them in Gehenna and they sat upon it and recited songs of praise. Rabba bar bar Ḥana said: One time I was walking on the path, and a certain Arab said to me: Come and I will show you those from the assembly of Korah who were swallowed. I went and I saw two fissures in the ground from which smoke was emerging. That Arab took a woolen fleece and dampened it with water and placed it on the tip of his spear and passed it over the fissures there. The fleece was singed, indicating the level of heat there. He said to me: Listen; what do you hear? And I heard that this is what they were saying: Moses and his Torah are truth, and they, referring to themselves, are liars.

א"ל כל תלתין יומין מהדרא להו גיהנם כבשר בתוך קלחת ואמרי הכי משה ותורתו אמת והן בדאים:

The Arab said to him: Every thirty days Gehenna returns them to this place like meat cooking in a cauldron, and they say this: Moses and his Torah are truth, and they are liars.

(ז) בְּנֵ֖י קְהָ֑ת עַמִּינָדָ֣ב בְּנ֔וֹ קֹ֥רַח בְּנ֖וֹ אַסִּ֥יר בְּנֽוֹ׃
(7) The sons of Kohath: his son Amminadab, his son Korah, his son Assir,
(ח) אֶלְקָנָ֥ה בְנ֛וֹ וְאֶבְיָסָ֥ף בְּנ֖וֹ וְאַסִּ֥יר בְּנֽוֹ׃
(8) his son Elkanah, his son Ebiasaph, his son Assir,
