Numbers 26:8

5 Reuben, the eldest son of Israel: the children of Reuben; Hanoch, of whom cometh the family of the Hanochites: of Pallu, the family of the Palluites:

6 Of Hezron, the family of the Hezronites: of Carmi, the family of the Carmites.

7 These are the families of the Reubenites: and they that were numbered of them were forty and three thousand and seven hundred and thirty.

9 And the sons of Eliab; Nemuel, and Dathan, and Abiram. This is that Dathan and Abiram, which were famous in the congregation, who strove against Moses and against Aaron in the company of Korah, when they strove against the LORD:

10 And the earth opened her mouth, and swallowed them up together with Korah, when that company died, what time the fire devoured two hundred and fifty men: and they became a sign.

11 Notwithstanding the children of Korah died not.
