Matthew 16:20

Then charged he his disciples to tell no one that he was the Christ — Jesus himself had not said it expressly even to his apostles, but left them tb infer it from his doctrine and miracles. Neither was it proper the apostles should say this openly, before that grand proof of it, his resurrection. If they had, they who believed them would the more earnestly have sought to take and make him a king: and they who did not believe them would the snore vehemently have rejected and opposed such a Messiah.
