Numbers 16:29-31

New Revised Standard Version, Anglicised

²⁹ If these people die a natural death, or if a natural fate comes on them, then the Lord has not sent me. ³⁰ But 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.’

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