Numbers 16:2

“These are they who were called upon by the congregation, the leaders of their fathers’ tribes; they were the heads of divisions of Israel.”

Fire also came forth from Yahweh and consumed the 250 men who were bringing near the incense.

And the sons of Eliab: Nemuel and Dathan and Abiram. These are the Dathan and Abiram who were called upon by the congregation, who contended against Moses and against Aaron in the congregation of Korah, when they contended against Yahweh,

and what He did to Dathan and Abiram, the sons of Eliab, the son of Reuben, when the earth opened its mouth and swallowed them, their households, their tents, and every living thing that followed them, among all Israel—

Then they became envious of Moses in the camp, And of Aaron, the holy one of Yahweh,

Woe to them! For they have gone the way of Cain, and for pay they have poured themselves into the error of Balaam, and perished in the rebellion of Korah.
