Numbers 16:30-32

But if Jehovah make a new thing, and the ground open its mouth, and swallow them up, with all that appertain unto them, and they go down alive into Sheol; then ye shall understand that these men have despised Jehovah. And it came to pass, as he made an end of speaking all these words, that the ground clave asunder that was under them; and the earth opened its mouth, and swallowed them up, and their households, and all the men that appertained unto Korah, and all their goods.
