Numbers 26:9-11

American Standard Version

⁹ And the sons of Eliab: Nemuel, and Dathan, and Abiram. These are that Dathan and Abiram, who were called of the congregation, who strove against Moses and against Aaron in the company of Korah, when they strove against Jehovah, ¹⁰ and the earth opened its mouth, and swallowed them up together with Korah, when that company died; what time the fire devoured two hundred and fifty men, and they became a sign. ¹¹ Notwithstanding, the sons of Korah died not.
