Numbers 26:5-11

Reuben, the firstborn of Israel (Jacob), the sons of Reuben: of Hanoch, the family of the Hanochites; of Pallu, the family of the Palluites; of Hezron, the family of the Hezronites; of Carmi, the family of the Carmites. These are the families (clans) of the Reubenites; and those who were numbered of them were 43,730. The son of Pallu: Eliab. The sons of Eliab: Nemuel and Dathan and Abiram. These are the Dathan and Abiram who were called by the congregation, who contended against Moses and Aaron in the company of Korah, when they contended against the LORD, and the earth opened its mouth and swallowed them up along with Korah, when that company died, when the fire devoured two hundred and fifty men, so that they became a [warning] sign. But Korah’s sons did not die [because they did not participate in the rebellion].
