NOTES for Mat 21:1-17
Into almost every line of this story the evangelist places a parallel with biblical prophecies, and some of them are quoted directly in the text. But almost every quotation is interpreted and understood here in a new way: Jesus becomes the center of all the prophecies and psalms. And this newness is naturally dictated by the course of the events that follow: everything will be fulfilled both as expected and, at the same time, in a way completely different from what the disciples and the people accompanying Jesus expect.
He enters the holy city, but what awaits Him there is not triumph, but execution. He is greeted as King, but He will be condemned as an impostor and criminal. He cleanses the Jerusalem Temple, but soon He Himself will become the new Temple for those who follow Him after His Resurrection.
Christ shows a new way, not at all the one people expect, even His disciples. He will fulfill the prophecies in a new way, in a way that even the wisest of the wise will not think to read them. He does not do what we expect of Him; He calls us to follow Him into His new life, into a new Heaven and a new Earth.
