Numbers 16:27-30

27So they got away from around the tents of Korah, Dathan, and Abiram; and Dathan and Abiram came out and stood at the door of their tents, with their wives, their sons, and their little children.

28And Moses said: “By this you shall know that the Lord has sent me to do all these works, for I have not done them of my own will.

29If these men die naturally like all men, or if they are visited by the common fate of all men, then the Lord has not sent me.

30But if the Lord creates a new thing, and the earth opens its mouth and swallows them up with all that belongs to them, and they go down alive into the pit, then you will understand that these men have rejected the Lord.”
