Pallu’s son was Eliab.
Reuben’s sons were Hanoch, Pallu, Hezron, and Carmi.
Those were the families in Reuben’s family group. There was a total of 43,730 men.
Eliab had three sons—Nemuel, Dathan, and Abiram. Remember, Dathan and Abiram were the two leaders that turned against Moses and Aaron. They followed Korah when Korah turned against the Lord.
