And they immediately left the ship and their father, and followed him.
All Commentaries on Matthew 4:22 Go To Matthew 4
Theophylact of Ochrid
AD 1107

When the father becomes an impediment to virtue and reverence for God. When James and John saw the first two follow Christ, they rightly followed Christ as well, imitating their good example.
