17From that time Jesus began to preach, and to say, Repent: for the kingdom of heaven is at hand. 18And Jesus, walking by the sea of Galilee, saw two brethren, Simon called Peter, and Andrew his brother, casting a net into the sea: for they were fishers. 19And he saith unto them, Follow me, and I will make you fishers of men. 20And they straightway left their nets, and followed him.21And going on from thence, he saw other two brethren, James the son of Zebedee, and John his brother, in a ship with Zebedee their father, mending their nets; and he called them. 22And they immediately left the ship and their father, and followed him. 23And 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.
