Matthew 4:25

With His fame grew the number of His followers: And there followed Him great multitudes of people from Galilee, and from Decapolis, and from Jerusalem, and from Judea, and from beyond Jordan.

The extraordinary impression which this Prophet of Nazareth created was not confined to Galilee. People came from Decapolis, the southern part of Gaulanitis, southeast of Lake Gennesaret, whose population was predominantly Grecian. They thought nothing of the long journey from the extreme South, from haughty Judea, from exclusive Jerusalem, from far-distant Perea, beyond the Jordan from Judea. All wanted to see and hear the man whose miracles were astounding the nation.

Summary. Jesus, having successfully withstood the temptation of the devil after His forty-day fast, entered upon His Galilean ministry of teaching, preaching, and healing, Peter, Andrew, James, and John being His first disciples.
