Numbers 16:30-32

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]
