Midrasz do Liczb 2:10

5 (Numb. 16:1) “[Korah who is] the son of Izhar [who is] the son of Kohath [who is] the son of Levi betook himself”: But why is it not written "the son of Jacob" [or] "the son of Israel?"¹³ Cf.Gen. R. 98:5. This text is related (to Gen. 49:6), “Let not my soul come into their council,” i.e., that of the spies; “and let not my glory be joined with their congregation,” i.e., that of Korah. Jacob said to the Holy One, blessed be He, “Master of the world, with reference to the spies and with reference to the dissension of Korah, let not my name be mentioned [in connection with] those evil men, who are going to cause provocation. So when should my name (Israel) be joined upon them? When they are joined together to stand on the dais (as Levitical singers), as stated (I Chron. 6:[17,] 22–23) ‘[These are the ones whom David put in charge of song in the house of the Lord….] The son of Assir [who is] the son of Ebiasaph [who is] the son of Korah [who is] the son of Izhar [who is] the son of Kohath [who is] the son of Levi [who is] the son of Israel.’” (Numb. 16:1, cont.) “Along with Dathan and Abiram”: From here the sages said, “Woe to the wicked one, [and] woe to his neighbor.”¹⁴See Neg. 12:6; Sifra to Lev.14:40 (157: Metsora‘, pereq 4); ARN, A, 9; cf. ARN, B, 16; Numb.R. 3:12; Suk. 56b; above, Numb.1:13. Dathan and Abiram [were destroyed by the dissent of Korah], because they were neighbors of Korah. As he was dwelling to the south (of the tabernacle), as stated (in Numb. 3:29), “The families of the Children of Kohath were to camp along the side of the tabernacle to the south.” The standard of Reuben was near them, as stated (in Numb. 2:10), “The standard of the camp of Reuben shall be to the south.” However, the standard of Judah was in the east, and with him were Issachar and Zebulun, as stated (in Numb. 2:3), “Now these camping in front to the east shall be the standard of the camp of Judah.” And near them were Moses and Aaron, as written (in Numb. 3:38), “Those who camped before the tabernacle, in front before the tent of meeting to the east, were Moses, Aaron, and his children.” Because these were near the Torah, they were therefore worthy to be Torah scholars, as written (in Ps. 60:9), “Judah is my lawgiver.”¹⁵Mehoqeq. Most translations render the word as scepter, since kingship was what Judah actually attained. And it is [also] written (in I Chron. 12:33), “And from the Children of Issachar, those who had an understanding of the times.” And it is [also] written (in Jud. 5:14), “and from Zebulon those who wield the scribal pen.” But Dathan and Abiram, who were neighbors to Korah – the one responsible for the dissent – were struck with him and perished from the world.
