As Jesus walked alongside the Galilee Sea, he saw two brothers, Simon, who is called Peter, and Andrew, throwing fishing nets into the sea, because they were fishermen.
References for Matthew 4:18
"Come, follow me," he said, "and I'll show you how to fish for people."
Right away, they left their nets and followed him.
Continuing on, he saw another set of brothers, James the son of Zebedee and his brother John. They were in a boat with Zebedee their father repairing their nets. Jesus called them and
immediately they left the boat and their father and followed him.
