Matthew 16:19-21 Young's Literal Translation (YLT)
19 and I will give to thee the keys of the reign of the heavens, and whatever thou mayest bind upon the earth shall be having been bound in the heavens, and whatever thou mayest loose upon the earth shall be having been loosed in the heavens.'
20 Then did he charge his disciples that they may say to no one that he is Jesus the Christ.
21 From that time began Jesus to shew to his disciples that it is necessary for him to go away to Jerusalem, and to suffer many things from the elders, and chief priests, and scribes, and to be put to death, and the third day to rise.
Matthew 16:19-21 New International Version (NIV)
19 I will give you the keys of the kingdom of heaven; whatever you bind on earth will be[a] bound in heaven, and whatever you loose on earth will be[b] loosed in heaven.” 20 Then he ordered his disciples not to tell anyone that he was the Messiah.
Jesus Predicts His Death
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.
