Numbers 26:9-10

⁹Eliab's sons were Nemuel, Dathan, and Abiram. These were the same Dathan and Abiram who followed Korah when they challenged Moses and Aaron and rebelled against Yahweh.

¹⁰The earth opened its mouth and swallowed them up together with Korah when all his followers died. At that time, fire devoured 250 men, who became a warning sign.
