Mark 1:16-20

16As Jesus was walking beside the Sea of Galilee, He saw Simon and his brother Andrew. They were casting a net into the sea, for they were fishermen. 17“Come, follow Me,” Jesus said, “and I will make you fishers of men.” 18And at once they left their nets and followed Him.

19Going on a little farther, He saw James son of Zebedee and his brother John. They were in a boat, mending their nets. 20Immediately Jesus called them, and they left their father Zebedee in the boat with the hired men and followed Him.
