Mark 9:5-6

Mark explained Peter’s blunder in Mark 9:5 in Mark 9:6. He did it more fully than Luke did. Matthew did not give a reason for Peter’s words. Again Peter opposed Jesus’ sufferings and death, though he was not fully aware of what he was doing (cf. Mark 8:32). He evidently believed that Jesus was going to set up His kingdom immediately (cf. Acts 1:6).
