Numbers 16:30-32

But if Yahweh creates an entirely new thing and the ground opens its mouth and swallows them up with all that is theirs, and they go down to Sheol alive, then you will know that these men have spurned Yahweh.” And it happened that as he finished speaking all these words, the ground that was under them split open; and the earth opened its mouth and swallowed them up, and their households, and all the men who belonged to Korah with their possessions.
