Exodus 15:24

"And the whole congregation of the children of Israel murmured against Moses and Aaron in the wilderness:"

"And they said unto Moses, Because there were no graves in Egypt, hast thou taken us away to die in the wilderness? wherefore hast thou dealt thus with us, to carry us forth out of Egypt?"

"For which cause both thou and all thy company are gathered together against the LORD: and what is Aaron, that ye murmur against him?"

"And the LORD said unto Moses, Bring Aaron's rod again before the testimony, to be kept for a token against the rebels; and thou shalt quite take away their murmurings from me, that they die not."
