What is the meaning of Matthew 21:10-11?

10 And when he was come into Jerusalem, all the city was moved, saying, Who is this? 11 And the multitude said, This is Jesus the prophet of Nazareth of Galilee. (Matthew 21:10-11 KJV)

William Burkitt’s Commentary

This is not the first or only time that Jerusalem was moved and troubled at the appearance of Christ; at his birth, Mt 2:3 we read all Jerusalem was troubled, together with Herod; and now that he rides into Jerusalem, though in so mean a port, yet there is a new commotion. Jerusalem, instead of being thankful for his company, is troubled at his presence.

Thence learn, That such persons and places as have the greatest helps and privileges afforded to them, are not always the most answerable in their returns of thankfulness. It is not Christ’s presence with us, but his welcome to us, that makes us happy. Christ is daily taught in our synagogues, and preached in our streets; yet alas! multitudes are ignorant of him, and say, with the men of Jerusalem, when Christ was before their eyes, Who is this?
