Numbers 16:28-30

New Living Translation

²⁸ And Moses said, “This is how you will know that the Lord has sent me to do all these things that I have done—for I have not done them on my own. ²⁹ If these men die a natural death, or if nothing unusual happens, then the Lord has not sent me. ³⁰ But if the Lord does something entirely new and the ground opens its mouth and swallows them and all their belongings, and they go down alive into the grave,^[a] then you will know that these men have shown contempt for the Lord.”
