Numbers 26:8-11

8The son of Pallu: Eliab. 9The sons of Eliab: Nemuel, Dathan, and Abiram. These are the Dathan and Abiram who were 1called by the congregation, who fought against Moses and against Aaron in the group of Korah, when they fought against the Lord, 10and 2the earth opened its mouth and swallowed them up along with Korah, when that group died, 3when the fire devoured 250 men, so that they became a warning sign. 114The sons of Korah, however, did not die.
