Numbers 16:29-35

29If these men die a natural death, or if nothing unusual happens, then the Lord has not sent me.

30But 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, then you will know that these men have shown contempt for the Lord.”

31He had hardly finished speaking the words when the ground suddenly split open beneath them.

32The 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.

33So 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.

34All the people around them fled when they heard their screams. “The earth will swallow us, too!” they cried.

35Then fire blazed forth from the Lord and burned up the 250 men who were offering incense.
