Numbers 16:1, 31-33

As soon as he finished saying all this, the ground under them split apart and the earth opened its mouth and swallowed them and their households, and all those associated with Korah, together with their possessions. They went down alive into the realm of the dead, with everything they owned; the earth closed over them, and they perished and were gone from the community.
