Números 17:10

10 The Lord said to Moses, "Put back Aaron's staff in front of the ark of the covenant law, to be kept as a sign to the rebellious. This will put an end to their grumbling against me, so that they will not die."

10 And the Lord said to Moses, Put Aaron's rod back in front of the ark of witness, to be kept for a sign against this false-hearted people, so that you may put a stop to their outcries against me, and death may not overtake them.
