Matthew 4:23-25

KJV
[23] And Jesus went about all Galilee, teaching in their synagogues, and preaching the gospel of the kingdom, and healing all manner of sickness and all manner of disease among the people.
[24] And his fame went throughout all Syria: and they brought unto him all sick people that were taken with divers diseases and torments, and those which were possessed with devils, and those which were lunatick, and those that had the palsy; and he healed them.
[25] And there followed him great multitudes of people from Galilee, and from Decapolis, and from Jerusalem, and from Judaea, and from beyond Jordan.


This is like the training montage in Rocky. Beiing a miracle worker was essential to the street cred of prophets at that time. If you can't cure blindness don't even call me. So the scribes who wrote the gospels just threw that in.

Notice he's very much a rock star in these three verses. It's interesting how differently Josh is portrayed from one chapter to the next. I'm sure it's due to trying to appease conflicting groups, but it makes for an interesting character portrayal, a complex, conflicted character.

Notice he's known for his healing and not his teachings. I wonder if I detect a certain cynicism here: the prophet no one really listened to.
