Numbers 16:29-35

29If these men die the common death of all men, or if they be visited after the visitation of all men; then Yhwh hath not sent me.1 30But if Yhwh make a new thing, and the earth open her mouth, and swallow them up, with all that appertain unto them, and they go down quick into the pit; then ye shall understand that these men have provoked Yhwh.2

31And it came to pass, as he had made an end of speaking all these words, that the ground clave asunder that was under them: 32And the earth opened her mouth, and swallowed them up, and their households, and all the men that appertained unto Korah, and all their goods. 33They, and all that appertained to them, went down alive into the pit, and the earth closed upon them: and they perished from among the congregation. 34And all Israel that were round about them fled at the cry of them: for they said, Lest the earth swallow us up also. 35And there came out a fire from Yhwh, and consumed the two hundred and fifty men that offered incense.
