Numbers 26:9-11
26:9 Eliab’s descendants were Nemuel, Dathan, and Abiram. It was Dathan and Abiram who as leaders of the community rebelled against Moses and Aaron with the followers of Korah when they rebelled against the Lord.
26:10 The earth opened its mouth and swallowed them and Korah at the time that company died, when the fire consumed 250 men. So they became a warning.
26:11 But the descendants of Korah did not die.
