³ John and his message were authorized by Isaiah’s prophecy:

^4-6 John dressed in a camel-hair habit tied at the waist by a leather strap. He lived on a diet of locusts and wild field honey. People poured out of Jerusalem, Judea, and the Jordanian countryside to hear and see him in action. There at the Jordan River those who came to confess their sins were baptized into a changed life.
