Numbers 16:29-31

Holman Christian Standard Bible

²⁹ If these men die naturally as all people would, and suffer the fate of all, then the Lord has not sent me. ³⁰ But if the Lord brings about something unprecedented, and the ground opens its mouth and swallows them along with all that belongs to them so that they go down alive into Sheol, then you will know that these men have despised the Lord.”

³¹ Just as he finished speaking all these words, the ground beneath them split open.
