Numbers 26:5-11

Reuben was the firstborn of Israel. The children of Reuben were: 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 of the Reubenites: those who were numbered of them were forty-three thousand seven hundred and thirty. And the son of Pallu was Eliab. The sons of Eliab were Nemuel, Dathan, and Abiram. These are the Dathan and Abiram, representatives of 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 together with Korah when that company died, when the fire devoured two hundred and fifty men; and they became a sign. Nevertheless the children of Korah did not die.
