An unusually large shark might fulfill the conditions of Jonah's fish (daÌ„gh, daÌ„ghaÌ„h; but , κῆτος, keÌ„Ìtos, “whale†or “sea monsterâ€). The whale that is found in the Mediterranean (Balaena australis) has a narrow throat and could not swallow a man. No natural explanation is possible of Jonah's remaining alive and conscious for three days in the creature's belly. Those who consider the book historical must regard the whole event as miraculous. For those who consider it to be a story with a purpose, no explanation is required.
3. Fishing
The present inhabitants of Moab and Edom make no use of the fish that swarm in the Arnon, the HÌ£isa and other streams, but fishing is an important industry in Galilee and Western Palestine. Now, as formerly, spear hooks and nets are employed. The fish-spear () is little used. Most of the Old Testament references to nets have to do with the taking of birds and beasts and not of fishes, and, while in hÌ£eÌ„rem is rendered “net†and mikhmereth “drag,†it is hot clear that these and the other words rendered “net†refer to particular kinds of nets. In the New Testament, however, σαγηÌνη, sageÌ„ÌneÌ„ (), is clearly the dragnet, and ἀμφιÌβληστÏον, amphıÌbleÌ„stron (), is clearly the casting net. The word most often used is διÌκτυον, dıÌktuonÌŒ. Though this word is from dikeıÌn, “to throw,†or “to cast,†the context in several places (e.g. ; ) suggests that a dragnet is meant. The dragnet may be several hundred feet long. The upper edge is buoyed and the lower edge is weighted. It is let down from a boat in a line parallel to the shore and is then pulled in by ropes attached to the two ends, several men and boys usually pulling at each end. The use of the casting net requires much skill. It forms a circle of from 10 to 20 feet in diameter with numerous small leaden weights at the circumference. It is lifted by the center and carefully gathered over the right arm. When well thrown it goes to some distance, at the same time spreading out into a wide circle. A cord may be attached to the center, but this is not always the case. When lifted again by the center, the leads come together, dragging over the bottom, and sometimes a large number of fish may be enclosed. The novice has only to try, to realize the dexterity of the practiced fishermen.
Figurative: The fact that so many of our Lord's disciples were fishermen lends a profound interest to their profession. Christ tells Simon and Andrew (; ) that He will make them fishers of men. The Kingdom of Heaven () is likened unto a net that was cast into the sea, and gathered of every kind; which, when it was filled, they drew up on the beach; and they sat down and gathered the good into vessels, but the bad they cast away. Tristram (NHB) says that he has seen the fishermen go through their net and throw out into the sea those that were too small for the market or were considered unclean. In , we read: “Behold, I will send for many fishers, saith Yahweh, and they shall fish them up; and afterward I will send for many hunters, and they shall hunt them from every mountain, and from every hill, and out of the clefts of the rocks.†In the vision of Ezekiel ( f), the multitude of fish and the nets spread from En-gedi to En-eglaim are marks of the marvelous change wrought in the Dead Sea by the stream issuing from the temple. The same sign, i.e. of the spreading of nets (, ), marks the desolation of Tyre. It is a piece of broiled fish that the risen Lord eats with the Eleven in Jerusalem (), and by the Sea of Galilee () He gives the disciples bread and fish.
