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.”

³¹ He had hardly finished speaking the words when the ground suddenly split open beneath them. ³² The earth opened its mouth and swallowed the men, along with their households and all their followers who were standing with them, and everything they owned. ³³ So they went down alive into the grave, along with all their belongings. The earth closed over them, and they all vanished from among the people of Israel. ³⁴ All the people around them fled when they heard their screams. “The earth will swallow us, too!” they cried. ³⁵ Then fire blazed forth from the Lord and burned up the 250 men who were offering incense.
