Num 26:5-10

5Reuben, the firstborn of Israel. The descendants of Reuben: of Hanoch, the clan of the Hanochites; of Pallu, the clan of the Palluites;6of Hezron, the clan of the Hezronites; of Carmi, the clan of the Carmites.7These are the clans of the Reubenites; the number of those enrolled was forty-three thousand seven hundred thirty.8And the descendants of Pallu: Eliab.9The descendants of Eliab: Nemuel, Dathan, and Abiram. These are the same Dathan and Abiram, chosen from the congregation, who rebelled against Moses and Aaron in the company of Korah, when they rebelled against the Lord,10and the earth opened its mouth and swallowed them up along with Korah, when that company died, when the fire devoured two hundred fifty men; and they became a warning.
