Bamidbar 16:30-32

But if HASHEM creates a new thing, and haadamah open her mouth, and swallow them up, with all that appertain unto them, and they go down chayyim into Sheol; then ye shall have da'as that these men have spurned HASHEM. And it came to pass, as he had made an end of speaking all these devarim, that haadamah split asunder that was under them: And ha'aretz opened her mouth, and swallowed them up, their batim (houses), all the men that were of Korach, and all their possessions.
