Numbers 26:5-9

The tribe of Reuben, the first son born to Israel, was counted. From Hanoch came the Hanochite family group; from Pallu came the Palluite family group; from Hezron came the Hezronite family group; from Carmi came the Carmite family group. These were the family groups of Reuben, and the total number of men was 43,730. The son of Pallu was Eliab, and Eliab’s sons were Nemuel, Dathan, and Abiram. Dathan and Abiram were the leaders who turned against Moses and Aaron and followed Korah when he turned against the LORD.
