Numbers 16:28-30

Thomson(i) 28 And Moses said, By this you shall know that the Lord hath sent me to do all these works, and that they are not of myself; 29 If these men die the common death of all men; or if their visitation be according to the visitation of all men, the Lord hath not sent me: 30 but if the Lord demonstrate by a miracle, and the earth opening its mouth, shall swallow up them and their households, and their tents, and all that belong to them; and they go down alive to the mansion of the dead; then you will know that these men have provoked the Lord.
