Jesus takes the twelve aside. They, in particular, need to understand why their Master is determined to go to Jerusalem (Luke 9:51). Very special things are going to happen there with the Son of Man, about whom the prophets had already spoken earlier. This designation Son of Man
primarily emphasizes that he is a son of Adam. There is also something mysterious about this title (see Daniel 7:13ff.). It indicates that Jesus is more than just a human being!
31 Jésus prit les douze auprès de lui, et leur dit: Voici, nous montons à Jérusalem, et tout ce qui a été écrit par les prophètes au sujet du Fils de l'homme s'accomplira.
