Christians argue that the first cock-crow is simply missing from Matthew, Luke, and John. In Matthew (), Luke (), and John (), Jesus foretells three denials of Peter before cock-crow. , , report the fulfillment of this prophecy. In , Jesus speaks of two cock-crows, which is mentioned in as having taken place. Christians argue that Matthew, Luke, and John removed the first cock-crow and diminished (Luke even eliminated) the partial exit by Peter after the first denial (which Mark reports). If Mark was the "interpreter of Peter", he would have gotten his information directly and thus would be considered the more reliable source.
