Mc 1:16-20
As he passed by the Sea of Galilee, he saw Simon and his brother Andrew casting their nets into the sea; they were fishermen. Jesus said to them, "Come after me, and I will make you fishers of men." Then they abandoned their nets and followed him. He walked along a little farther and saw James, the son of Zebedee, and his brother John. They too were in a boat mending their nets. Then he called them. So they left their father Zebedee in the boat along with the hired men and followed him.
