Numbers 16:31-35, 49

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. All Israel who were around them fled at their outcry, for they said, “The earth may swallow us up!” Fire also came forth from the LORD and consumed the two hundred and fifty men who were offering the incense.

But those who died by the plague were 14,700, besides those who died on account of Korah.
