Numbers 16:28-32

And Moses said, Hereby ye shall know that the LORD hath sent me to do all these works; for I have not done them of mine own mind.

If these men die the common death of all men, or if they be visited after the visitation of all men; then the LORD hath not sent me.

But if the LORD make a new thing, and the earth open her mouth, and swallow them up, with all that appertain unto them, and they go down quick into the pit; then ye shall understand that these men have provoked the LORD.

And it came to pass, as he had made an end of speaking all these words, that the ground clave asunder that was under them:

And the earth opened her mouth, and swallowed them up, and their houses, and all the men that appertained unto Korah, and all their goods.
