Numbers 16:28-30

Darby Translation

²⁸ And Moses said, Hereby ye shall know that Jehovah has sent me to do all these deeds, for they are not out of my own heart:

²⁹ if these men die as all men die, and are visited with the visitation of all men, Jehovah has not sent me;

³⁰ but if Jehovah make a new thing, and the ground open its mouth, and swallow them up, and all that they have, and they go down alive into Sheol, then ye shall know that these men have despised Jehovah.
