Numbers 16:29-35

29If these men die the common death of all mankind or if what happens to everyone happens to them, then [you will know for sure that] the Lord has not sent me.

30But if the Lord creates an entirely new thing, and the ground opens its mouth and swallows them up, along with all that belongs to them, and they descend alive into Sheol (the nether world, the place of the dead), then you will understand that these men have spurned and rejected the Lord!”

31As soon as Moses finished speaking all these words, the ground under them split open;

32and the earth opened its mouth and swallowed them and their households, and all the men who supported Korah, with all their possessions.

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

34All Israel who were around them fled at their outcry, for they said, “The earth may swallow us also.”

35Fire also came forth from the Lord and consumed the two hundred and fifty men who were offering the incense.
