Numbers 16:26-35

And he said to the congregation, “Get away from the tents of these wicked men, and touch nothing of theirs, or you will be swept away in all their sin.” So they got back from around the tents of Korah, Dathan, and Abiram; and Dathan and Abiram came out and stood at the doorway of their tents with their wives and their sons and their little children. Then Moses said, “By this you shall know that the LORD has sent me to do all these works; for I do not act of my own accord. If 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. But 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!” As soon as Moses finished speaking all these words, the ground under them split open; and the earth opened its mouth and swallowed them and their households, and all the men who supported Korah, with all their possessions. [Num 26:10, 11] So 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. All Israel who were around them fled at their outcry, for they said, “The earth may swallow us also.” Fire also came forth from the LORD and consumed the two hundred and fifty men who were offering the incense.
