There is a path which no fowl knoweth - That is, a path in searching for gold and precious stones. The miner treads a way which is unseen by the bird of keenest vision. He penetrates into the deep darkness of the earth. The object of Job is to show the wisdom and the intrepidity of man in penetrating these dark regions in searching for sapphires and gold. The most far-sighted birds could not find their way to them. The most intrepid and fearless beasts of prey dared not adventure to those dangerous regions. The word rendered "fowl" (עיט ‛ayı̂ṭ) means either a ravenous beast, Jeremiah 12:9, or more commonly a ravenous bird; see the notes at Isaiah 46:11. According to Bochart, Hieroz. P. 11. L. 11. c. viii. p. 195, the word here denotes a rapacious bird of any kind; a bird which has a keen vision.
Which the vulture's eye hath not seen - The vulture is distinguished for the remarkable keenness of its vision. On the deserts of Arabia, it is said, when a camel dies, there is almost immediately discerned far in the distant sky, what seems at first to be a mere speck. As it draws nearer it is perceived to be a vulture that had marked the camel as he fell, and that comes to prey upon it. This bird is proverbial for the keenness of its sight.

There is a path which no fowl knoweth - The instinct of birds is most surprising. They traverse vast forests, etc., in search of food, at a great distance from the place which they have chosen for their general residence; and return in all weathers, never missing their track: they also find their own nest without ever mistaking another of the same kind for it. Birds of passage, also, after tarrying in a foreign clime for six or seven months, return to their original abode over kingdoms and oceans, without missing their way, or deviating in the least from the proper direction; not having a single object of sight to direct their peregrinations. In such cases even the keen scent of the vulture, and the quick, piercing sight of the eagle, would be of no use. It is possible that Job may here refer to undiscovered mines and minerals; that notwithstanding man had already discovered much, yet much remained undiscovered, especially in the internal structure and contents of the earth. Since his time innumerable discoveries have been made; and yet how little do we know! Our various conflicting and contradictory theories of the earth are full proofs of our ignorance, and strong evidences of our folly. The present dogmatical systems of geology itself are almost the ne plus ultra of brain-sick visionaries, and system-mad mortals. They talk as confidently of the structure of the globe, and the manner and time in which all was formed, as if they had examined every part from the center to the circumference; though not a soul of man has ever penetrated two miles in perpendicular depth into the bowels of the earth. And with this scanty, defective knowledge, they pretend to build systems of the universe, and blaspheme the revelation of God! Poor souls! All these things are to them a path which no fowl knoweth, which the vulture's eye hath not seen, on which the lion's whelps have not trodden, and by which the fierce lion have not passed. The wisdom necessary to such investigations is out of their reach; and they have not simplicity of heart to seek it where it may be found. One of the Chaldee Targums gives a strange turn to this verse: - "The path of the tree of life Sammael, (Satan), though flying like a bird, hath not known; nor hath the eye of Eve beheld it. The children of men have not walked in it; nor hath the serpent turned towards it."

There is a path which no fowl knoweth,.... A path made by miners to the gold, silver, brass, and iron ores; to the places where gems and precious stones lie; the way to which was never seen, and could never have been discovered by the most sharp-sighted fowl, as "the eagle" (d); which some think is particularly intended; and the Greek word for an eagle seems to be derived from the word used in the text: this fowl, the king of birds, as it is the swiftest, it is the most quick-sighted of any; but, though it is eager, and looks out sharp after its prey, and which it beholds at a great distance, and in the most secret lurking places, and flies unto it, and seizes upon it at once, yet it never could look into the bowels of the earth, or discover a track leading thereunto; in this it is outdone by the diligent and laborious miner, who is not at a loss to make his way into the inmost and darkest recesses of the earth:
which the vulture's eye hath not seen; which is next to the eagle, and some of them are of the species of it, and is a very sharp-sighted creature, even to a proverb, as well as voracious, which makes it diligent to search everywhere for its prey; and yet this creature's sharp and piercing eye never saw the path the miners make by digging into the earth, in order to get metals and minerals from it. Some understand this path of subterraneous paths in nature, made of God, through which rivers of water pass that were never seen by creatures of the quickest sight; it may rather be applied to the paths of God in providence, which are unsearchable and past finding out, by men of the most sagacious and penetrating capacities, though they will hereafter be made manifest; and also to his paths of love, grace, and mercy towards the sons of men, which are the deep things of God, searched into and revealed by his Spirit, or otherwise could not be known; as well as to the ways and paths of righteousness and holiness, of faith and truth, of the word and ordinances God has revealed, as his mind and will his people should walk in, which otherwise would not be known, and are not by carnal men; and especially to the principal way and path, Christ Jesus, who is the way to the Father, the way to everlasting happiness, the way of life and salvation, the high way and way of holiness, in which men, though fools, shall not err, and of which some things are said in Isaiah 35:8; which greatly agree with what are said of this path, here and in Job 28:8, this way of peace is not known by carnal men, nor the things of it discerned by natural men, though ever so sagacious; see Romans 3:17.
(d) "ad id alludit aquiae Graecum vocabulum" Bochart. Hierozoic par. 1. l. 1. c. 9. col. 59. Broughton renders it "a kite".

fowl--rather, "ravenous bird," or "eagle," which is the most sharp-sighted of birds (Isaiah 46:11). A vulture will spy a carcass at an amazing distance. The miner penetrates the earth by a way unseen by birds of keenest sight.

A path - In the bowels of the earth. Vulture's eye - Whose eye is very quick, and strong, and searcheth all places for its prey.
