Exodus 6:18 connects this Korah with Hebron, Uzziel and Amram, who were his father's brothers (Izhar son of Kohath).
[3] Korah is represented as the possessor of extraordinary wealth, having discovered one of the treasures that Joseph had hidden in Egypt.
[4] He and Haman were the two richest men in the world, and both died on account of their greed, and because their riches were not the gift of Heaven.
[5] On the other hand, Korah is represented as a wise man, chief of his family and as one of the Kohathites who carried the Ark of the Covenant on their shoulders.
[9] Korah asked Moses the following questions: "Does a tallit made entirely of tekhelet need fringes?"
He then assembled 250 men, chiefs of the Sanhedrin, and, having clad them in tallitot of blue wool, but without fringes, prepared for them a banquet.
Aaron's sons came for the priestly share, but Korah and his people refused to give the prescribed portions to them, saying that it was not God but Moses who commanded those things.
When she came to plow it, Moses told her not to plow it with an ox and an ass together;[16] when she came to sow it, Moses told her not to sow it with mingled seeds;[17] At the time of harvest she had to leave unreaped the parts of the field prescribed by the Law, while from the harvested grain she had to give the priest the share due to him.
Aaron replied: 'In that case the whole belongs to me',[20] whereupon he took away the meat, leaving the widow and her two daughters wholly unprovided for".
[21] The question how it was possible for a wise man like Korah to be so imprudent as to rebel is explained by the fact that he was deceived through his own prophetic ability.
[24] He and his followers continued to sink until Hannah prayed for them;[25] and through her prayer, the Rabbis declare, Korah will ascend to paradise.
On placing his ear to the slit, he heard voices cry: "Moses and his Torah are true; and we are liars".
(NIV) The rebellion of Korah is also made reference to in chapter 11 of 2 Meqabyan, a book considered canonical in the Ethiopian Orthodox Tewahedo Church.
Korah is also mentioned by Irenaeus in his anti-Gnostic work Against Heresies (Koinē Greek: Ἔλεγχος καὶ ἀνατροπὴ τῆς ψευδωνύμου γνώσεως), written in about 180.
Specifically he wrote that there are some who "declare that Cain derived his being from the Power above, and acknowledge that Esau, Korah, the Sodomites, and all such persons, are related to themselves."
Indeed, Allah does not like the exultant.The Quran states he was punished due to his extreme arrogance by being swallowed by earth along with all his great material wealth.
