Numbers 16:30-33

30But if the LORD brings about something unprecedented, and the earth opens its mouth and swallows them and all that belongs to them so that they go down alive into Sheol, then you will know that these men have treated the LORD with contempt.”

31As soon as Moses had finished saying all this, the ground beneath them split open, 32and the earth opened its mouth and swallowed them and their households—all Korah’s men and all their possessions. 33They went down alive into Sheol with all they owned. The earth closed over them, and they vanished from the assembly.
