(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. (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 Adonai is in their midst. Why then do you raise yourselves above the Adonai's congregation?”
עדת קרח אין להם חלק לעולם הבא, שנאמר (במדבר טז, לג): ותכס עליהם הארץ- בעולם הזה, ויאבדו מתוך הקהל- לעולם הבא, דברי ר"ע.
רבי אליעזר אומר: עליהם אמר הכתוב (שמואל א ב, ו): ה' ממית ומחיה מוריד שאול ויעל:
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 Eliezer says: About the assembly of Korah, the verse states: “Adonai causes death and causes life; God lowers to Sheol, and raises up” (I Samuel 2:6),
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).
אמר רב: און בן פלת אשתו הצילתו. אמרה ליה: מאי נפקא לך מינה? אי מר רבה, אנת תלמידא, ואי מר רבה אנת תלמידא!
אמר לה: מאי אעביד הואי? בעצה ואשתבעי לי בהדייהו.
אמרה ליה: ידענא דכולה כנישתא קדישתא נינהו דכתיב (במדבר טז, ג) כי כל העדה כולם קדושים.
אמרה ליה: תוב, דאנא מצילנא לך. אשקיתיה חמרא, וארויתיה ואגניתיה גואי אותבה על בבא, וסתרתה למזיה כל דאתא חזיה הדר אדהכי והכי אבלעו להו.
Rav says: On, son of Peleth, did not repent on his own; rather, his wife saved him. She said to him: What is the difference to you? If this Master, Moses, is the great one, you are the student. And if this Master, Korah, is the great one, you are the student. Why are you involving yourself in this matter? On said to her: What shall I do? I was one of those who took counsel and I took an oath with them that I would be with them. She said to him: I know that the entire assembly is holy, as it is written: “For all the assembly is holy” (Numbers 16:3), [and will act properly]. She said to him: Sit, for I will save you. She gave him wine to drink and caused him to become drunk and laid him on a bed inside their tent. She sat at the entrance of the tent and exposed her hair as though she were bathing. Anyone who came and saw her stepped back. In the meantime the assembly of Korah was swallowed into the ground, and On, son of Peleth, was spared.
