Numbers 16:30-32

But 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.” As soon as he had finished saying all this, the ground under them split, and the earth opened up to swallow them, their families, the followers of Korah, and all their property.
