Numbers 16
29 Ref If these men die the common death of all men, or if they be visited after the visitation of all men; then Yahweh hasn't sent me.
30 Ref But if Yahweh make a new thing, and the ground open its mouth, and swallow them up, with all that appertain to them, and they go down alive into Sheol; then you shall understand that these men have despised Yahweh.
