Webster(i)
28 And Moses said, by this ye shall know that the LORD hath sent me to do all these works: for I have not done them of my own mind.
29 If these men shall 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 shall make a new thing, and the earth shall open her mouth, and swallow them up, with all that appertain to them, and they go down quick into the pit; then ye shall understand that these men have provoked the LORD.
