Numbers 16:30-33

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.
