16Now as he walked by the sea of Galilee, he saw Simon and Andrew his brother casting a net into the sea: for they were fishers. 17And Jesus said unto them, Come ye after me, and I will make you to become fishers of men. 18And straightway they forsook their nets, and followed him. 19And when he had gone a little further thence, he saw James the son of Zebedee, and John his brother, who also were in the ship mending their nets.20And straightway he called them: and they left their father Zebedee in the ship with the hired servants, and went after him. 21And they went into Capernaum; and straightway on the sabbath day he entered into the synagogue, and taught. 22And they were astonished at his doctrine: for he taught them as one that had authority, and not as the scribes.
