Numbers 16:28-30 English Revised Version (ERV)

28. 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.

29. 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.

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