Matthew 3

The fulfillment of a prophesy starts chapter 3.  John the Baptist came from the wilderness preaching repentance to fulfill what the prophet Isiah prophesied.  When John was baptizing he saw the Pharisees and Sadducees coming to his baptism and said that every tree that does not bear fruit will be cut down and thrown in the fire.  He humbled himself by saying that he only baptized with water, but one greater than him would baptize with the Holy Spirit and fire.  When Jesus came to be baptized John at first said no for Jesus should be baptizing him and not John baptizing Jesus.  John did baptize Jesus and when he did the heavens opened up and the Spirit of God descended on Jesus like and dove and a voice said that this was his son in whom he was well pleased.
