Matthew 16:20
Then he strictly charged the disciples to tell no one that he was the Christ. The command to silence after Peter's confession is the Messianic Secret at its most direct: the disciples have correctly identified Jesus, but the identification must not be publicly announced at this stage. The reason becomes clear in the following verses: the Christ that the disciples have confessed is the suffering, dying, rising Christ — not the triumphant political messiah the public expects.
