Mark 1:16-22

16And as He walked by the Sea of Galilee, He saw Simon and Andrew his brother casting a net into the sea; for they were fishermen.

17Then Jesus said to them, “Follow Me, and I will make you become fishers of men.”

18They immediately left their nets and followed Him.

19When He had gone a little farther from there, He saw James the son of Zebedee, and John his brother, who also were in the boat mending their nets.

20And immediately He called them, and they left their father Zebedee in the boat with the hired servants, and went after Him.

21Then they went into Capernaum, and immediately on the Sabbath He entered the synagogue and taught.

22And they were astonished at His teaching, for He taught them as one having authority, and not as the scribes.
