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