Job 41:32

“He maketh a path to shine after him, etc.] Upon the sea, by raising a white from upon it, through its vehement motion as it passes along, or by the spermaceti it casts out and leaves behind it. It is said f1577 that whales will cut and plough the sea in such a manner, as to leave a shining glittering path behind them, the length of a German mile, which is three of ours; [one] would think the deep [to be] hoary; to be old and grey headed, or white like the hair of the head of an old man, a figure often used of the sea by poets f1578; and hence “Nereus” f1579, which is the sea, is said to be an old man, because the froth in the waves of it looks like white hair.”

“path--the foam on his track. hoary--as hair of the aged.”

“He maketh a path to shine after him - This refers doubtless to the white foam of the waters through which he passes. If this were spoken of some monster that commonly resides in the ocean, it would not be unnatural to suppose that it refers to the phosphoric light such as is observed when the waters are agitated, or when a vessel passes rapidly through them. If it refers, however, to the crocodile, the allusion must be understood of the hoary appearance of the Nile or the lake where he is found. One would think the deep to be hoary - Homer often speaks of the sea as πολιὴν θάλασσαν poliēn thalassan - “the hoary sea.” So Apollonius, speaking of the Argonauts, Lib. i. 545: - μακραὶ δ ̓…”

“Shine - By the white froth or foam upon the waters. The same may be observed in the wake of a ship by night. Job 41:34”

“By his rapid passage through the water he makes it white with foam; and by his tail he causes the waves behind him to sparkle like a trail of light. to shine: Gen 1:15 deep: Job 28:14, Job 38:16, Job 38:30; Gen 1:2 hoary: Gen 15:15, Gen 25:8, Gen 42:38; Pro 16:31, Pro 20:29 Job 41:33”
