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 Jehovah said unto Moses, Put back the rod of Aaron before the testimony, to be kept for a token against the children of rebellion; that thou mayest make an end of their murmurings against me, that they die not.
