Numbers 26:8-10

New King James Version

⁸ And the son of Pallu was Eliab. ⁹ The sons of Eliab were Nemuel, Dathan, and Abiram. These are the Dathan and Abiram, ^(A)representatives of the congregation, who contended against Moses and Aaron in the company of Korah, when they contended against the Lord; ^10 (B)and the earth opened its mouth and swallowed them up together with Korah when that company died, when the fire devoured two hundred and fifty men; ^(C)and they became a sign.
