Numbers 16:33-37

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.

Then all Israel who were around them fled at their outcry, for they said, “The earth might swallow us!”

Fire also came out from the Lord and consumed the 250 men who were offering the incense.

Then the Lord spoke to Moses, saying,

“Tell Eleazar, the son of Aaron the priest, that he shall pick up the censers from the midst of the burned area, because they are holy; and you are to scatter the burning coals farther away.
