Numbers 16:29-35

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

30But if the Lord creates something new, and the ground opens its mouth and swallows them up with all that belongs to them, and they go down alive into Sheol, then you shall know that these men have despised the Lord."

31And as soon as he had finished speaking all these words, the ground under them split apart.

32And the earth opened its mouth and swallowed them up, with their households and all the people who belonged to Korah and all their goods.

33So they and all that belonged to them went down alive into Sheol, and the earth closed over them, and they perished from the midst of the assembly.

34And all Israel who were around them fled at their cry, for they said, "Lest the earth swallow us up!"

35And fire came out from the Lord and consumed the 250 men offering the incense.
