Numbers 16:27-30

27So they moved away from near the dwelling of Korah, Dathan and Abiram. Dathan and Abiram came outside and were standing at the entrance of their tents with their wives, their children, and their little ones.

28Moses said, “By this you will know that Adonai has sent me to do all these works, that they are not from my own heart.

29If every one of these men die a common death and experience what happens to all people, then Adonai has not sent me.

30But if Adonai brings about a new thing, and the earth opens her mouth and swallows them and everything that is theirs, and they go down alive into Sheol, then you will know that these men have despised Adonai.”
