Concise Bible Dictionary:
Fishing was very common in Egypt, not only with the net, but with the line and hook (Isa. 19:8); and the same were used by the Israelites, for nets are often referred to, and the fish that had the piece of money in its mouth was caught with a hook (Matt. 17:27). In Habakkuk 1:15 the same things are referred to symbolically for the catching of men for captivity. The apostles of the Lord were made fishers of men.
