Adam Clarke's Commentary on the Bible

Verse 7 (Job 28:7)

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."
