Diogenes Laertius, Lives of the Philosophers
2.6.48 (tr. R.D. Hicks):
The story goes that Socrates met him in a narrow passage, and that he stretched out his stick to bar his way, while he inquired where every kind of food was sold. Upon receiving a reply, he put another question," And where do men become good and honourable?" Xenophon was fairly puzzled; "Then follow me," said Socrates, "and learn." From that time onward he was a pupil of Socrates.
Matthew 4.18-22 (par. Mark 1.16-20):
And Jesus, walking by the sea of Galilee, saw two brethren, Simon called Peter, and Andrew his brother, casting a net into the sea: for they were fishers. And he saith unto them, Follow me, and I will make you fishers of men. And they straightway left their nets, and followed him. And going on from thence, he saw other two brethren, James the son of Zebedee, and John his brother, in a ship with Zebedee their father, mending their nets; and he called them. And they immediately left the ship and their father, and followed him.
