Numbers 26:9-11

and Eliab was the father of Nemuel, Dathan, and Abiram. This Dathan and Abiram are the same community leaders who conspired with Korah against Moses and Aaron, rebelling against the LORD. But the earth opened up its mouth and swallowed them with Korah, and fire devoured 250 of their followers. This served as a warning to the entire nation of Israel. However, the sons of Korah did not die that day.
