Numbers 16:30-33 NASB
But if the LORD brings about an entirely new thing and the ground opens its mouth and swallows them up with all that is theirs, and they descend alive into Sheol, then you will understand that these men have spurned the LORD.”
As he finished speaking all these words, the ground that was under them split open; and the earth opened its mouth and swallowed them up, and their households, and all the men who belonged to Korah with their possessions. So they and all that belonged to them went down alive to Sheol; and the earth closed over them, and they perished from the midst of the assembly.
