Numbers 16:27-32

27So they moved away from the tents of Korah, Dathan, and Abiram. Dathan and Abiram had come out and were standing at the entrances to their tents with their wives and children.

28Moses said, “This is how you will know that the Lord sent me to do all these things and that it wasn’t my idea:

29If these men die like all other people—if they die a natural death—then the Lord hasn’t sent me.

30But if the Lord does something totally new—if the ground opens up, swallows them and everything that belongs to them, and they go down alive to their graves—then you’ll know that these men have treated the Lord with contempt.”

31As soon as he had finished saying all this, the ground under them split,

32and the earth opened up to swallow them, their families, the followers of Korah, and all their property.
