refused to repent. The Gemara related the name On () in to the Hebrew word for "mourning" (, aninah) and deduced from On's name that he sat in lamentations. The Gemara related the name Peleth () in to the Hebrew word for "miracles" (pelaot) and deduced from Peleth's name that God performed wonders for him. And as the name Reuben () derived from the Hebrew words "see" (reu) and "understand" (, mavin), the Gemara deduced from the reference to On as a "son of Reuben" in that On was a son who saw and understood. Rabbi Joshua identified Dathan as the Israelite who asked Moses in , "Who made you a ruler and a judge over us?" reports that the Reubenite On son of Peleth joined Korah's conspiracy, but the text does not mention On again. Rav explained that On's wife saved him, arguing to him that no matter whether Moses or Korah prevailed, On would remain just a disciple. On replied that he had sworn to participate. So On's wife got him drunk with wine, and laid him down in their tent. Then she sat at the entrance of their tent and loosened her hair, so that whoever came to summon him saw her and retreated at the sight of her immodestly loosened hair. The Gemara taught that refers to On's wife when it says: "Every wise woman builds her house." The Mishnah in Pirkei Avot deduced that the controversy of Korah and his followers was not for the sake of Heaven, and thus was destined not to result in permanent change. The Mishnah contrasted Korah's argument to those between Hillel and Shammai, which the Mishnah taught were controversies for the sake of Heaven, destined to result in something permanent. Reading , “Cut not off the tribe of the families of the Kohathites from among the Levites,” Rabbi Abba bar Aibu noted that it would have been enough for the text to mention the family of Kohath, and asked why also mentions the whole tribe. Rabbi Abba bar Aibu explained that God (in the words of ), “declar[es] the end from the beginning,” and provides beforehand for things that have not yet occurred. God foresaw that Korah, who would descend from the families of Kohath, would oppose Moses (as reported in ) and that Moses would beseech God that the earth should swallow them up (as reflected in ).
