Numbers 16:1, 32

Korah, Dathan, Abiram, and On turned against Moses. (Korah was the son of Izhar, the son of Kohath, the son of Levi; Dathan and Abiram were brothers, the sons of Eliab; and On was the son of Peleth; Dathan, Abiram, and On were from the tribe of Reuben.)

The earth opened and swallowed them and all their families. All Korah’s men and everything they owned went down.
