One day Jesus was walking beside the Sea of Galilee. There he saw two brothers. They were Simon Peter and his brother Andrew. They were throwing a net into the lake. They were fishermen.
References for Matthew 4:18
"Come. Follow me," Jesus said. "I will make you fishers of people."
At once they left their nets and followed him.
Going on from there, he saw two other brothers. They were James, son of Zebedee, and his brother John. They were in a boat with their father Zebedee. As they were preparing their nets, Jesus called out to them.
Right away they left the boat and their father and followed Jesus.
