20 Then he ordered his disciples not to tell anyone that he was the Messiah.

20 He swore the disciples to secrecy. He made them promise they would tell no one that he was the Messiah.

21 From that time on Jesus began to explain to his disciples that he must go to Jerusalem and suffer many things at the hands of the elders, the chief priests and the teachers of the law, and that he must be killed and on the third day be raised to life.
21 From that time forth began Jesus to shew unto his disciples, how that he must go unto Jerusalem, and suffer many things of the elders and chief priests and scribes, and be killed, and be raised again the third day.

21 From then on Jesus began to tell his disciples plainly that it was necessary for him to go to Jerusalem, and that he would suffer many terrible things at the hands of the elders, the leading priests, and the teachers of religious law.

(Read Matthew 16:21-23)
Christ reveals his mind to his people gradually. From that time, when the apostles had made the full confession of Christ, that he was the Son of God, he began to show them of his sufferings. He spake this to set right the mistakes of his disciples about the outward pomp and power of his kingdom. Those that follow Christ, must not expect great or high things in this world. Peter would have Christ to dread suffering as much as he did; but we mistake, if we measure Christ's love and patience by our own. We do not read of any thing said or done by any of his disciples, at any time, that Christ resented so much as this. Whoever takes us from that which is good, and would make us fear to do too much for God, speaks Satan's language. Whatever appears to be a temptation to sin, must be resisted with abhorrence, and not be parleyed with. Those that decline suffering for Christ, savour more of the things of man than of the things of God.
Matthew Henry's Commentary on Matthew 16:20
Commentary on Matthew 16:13-20
(Read Matthew 16:13-20)
Peter, for himself and his brethren, said that they were assured of our Lord's being the promised Messiah, the Son of the living God. This showed that they believed Jesus to be more than man. Our Lord declared Peter to be blessed, as the teaching of God made him differ from his unbelieving countrymen. Christ added that he had named him Peter, in allusion to his stability or firmness in professing the truth. The word translated "rock," is not the same word as Peter, but is of a similar meaning. Nothing can be more wrong than to suppose that Christ meant the person of Peter was the rock. Without doubt Christ himself is the Rock, the tried foundation of the church; and woe to him that attempts to lay any other! Peter's confession is this rock as to doctrine. If Jesus be not the Christ, those that own him are not of the church, but deceivers and deceived. Our Lord next declared the authority with which Peter would be invested. He spoke in the name of his brethren, and this related to them as well as to him. They had no certain knowledge of the characters of men, and were liable to mistakes and sins in their own conduct; but they were kept from error in stating the way of acceptance and salvation, the rule of obedience, the believer's character and experience, and the final doom of unbelievers and hypocrites. In such matters their decision was right, and it was confirmed in heaven. But all pretensions of any man, either to absolve or retain men's sins, are blasphemous and absurd. None can forgive sins but God only. And this binding and loosing, in the common language of the Jews, signified to forbid and to allow, or to teach what is lawful or unlawful.
