Mark 1:16-20

As Jesus walked beside the Sea of Galilee, he saw Simon and his brother Andrew casting a net into the lake, for they were fishermen. 'Come, follow me,' Jesus said, 'and I will make you fishers of men.' At once they left their nets and followed him. When he had gone a little farther, he saw James son of Zebedee and his brother John in a boat, preparing their nets. Without delay he called them, and they left their father Zebedee in the boat with the hired men and followed him. Mark 1:16-20 NIV
