My apologies on the delay.  

The next time one of our terms shows up is in Chapter 11 of Matthew.  

In verses 11 & 12, βαπτιστης (2/12, 3/12) is used twice which translated means Baptist/Baptizer. 

Who is Jesus talking about? John the Baptist
Why is Jesus talking about him?  Well John's disciples just came to ask whether or not Jesus was the one to come. For John has been locked away in prison awaiting his death.  
What does Jesus have to say about John? Jesus calls John a prophet, and that he was the one prophesied to come who would announce the Christ.
How should we regard John? Highly.  For Jesus says that among those born of women there has arisen no one greater than John the Baptist. However, whoever is least in the kingdom of Heaven is greater than John.  
Why should we pay attention? The Kingdom of Heaven has suffered violence, the world does not want to hear the message of John the Baptist and persecutes him violently. So it should come as no surprise that this violence will come upon the one whom John foretold.
