Numbers 26:14 (KJV)

And the sons of Eliab; Nemuel, and Dathan, and Abiram. This is that Dathan and Abiram, which were famous in the congregation, who strove against Moses and against Aaron in the company of Korah, when they strove against the LORD:

And the earth opened her 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.

Notwithstanding the children of Korah died not.

The sons of Simeon after their families: of Nemuel, the family of the Nemuelites: of Jamin, the family of the Jaminites: of Jachin, the family of the Jachinites:

Of Zerah, the family of the Zarhites: of Shaul, the family of the Shaulites.

The children of Gad after their families: of Zephon, the family of the Zephonites: of Haggi, the family of the Haggites: of Shuni, the family of the Shunites:

Of Ozni, the family of the Oznites: of Eri, the family of the Erites:

Of Arod, the family of the Arodites: of Areli, the family of the Arelites.

These are the families of the children of Gad according to those that were numbered of them, forty thousand and five hundred.

The sons of Judah were Er and Onan: and Er and Onan died in the land of Canaan.
