Numbers 16:26-29 New International Version (NIV)

26. He warned the assembly, “Move back from the tents of these wicked men! Do not touch anything belonging to them, or you will be swept away because of all their sins.”

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

28. Then Moses said, “This is how you will know that the Lord has sent me to do all these things and that it was not my idea:

29. If these men die a natural death and suffer the fate of all mankind, then the Lord has not sent me.
