Numbers 26:8-10

⁸And the sons of Phallu were Eliab, —

⁹and the sons of Eliab, Namuel, and Dathan, and Abiron: these are renowned men of the congregation; these are they that rose up against Moses and Aaron in the gathering of Core, in the rebellion against the Lord.

¹⁰And the earth opened her mouth, and swallowed up them and Core, when their assembly perished, when the fire devoured the two hundred and fifty, and they were made a sign.
