Matthew 3:13

Then cometh Jesus - The Saviour is now introduced as about to enter on his work, or as about to be solemnly set apart to his great office of Messiah and Redeemer. The expression “cometh” implies that the act was voluntary on his part; that he went for that purpose and for no other. He left the part of Galilee - Nazareth - where he had lived for nearly 30 years, and went to the vicinity of the Jordan, where John was baptizing the people in great numbers, that he might be set apart to his work. The occasion was doubtless chosen in order that it might be as public and solemn as possible. It is to be remembered, also, that it was the main purpose of John’s appointment to introduce the Messiah to the world, Matthew 3:3.

To be baptized of him - By him. Baptism was not in his case a symbol of personal reformation and repentance, for he was sinless; but it was a solemn rite by which he was set apart to his great office. It is true, also, that although he was personally holy, and that the baptism in his case had a different signification, in this respect, from that which is implied when it is administered now, yet that even in his case the great idea always implied in the ordinance of baptism had a place; for it was a symbol of holiness or purity in that great system of religion which he was about to set up in the world.
