John Gill's Exposition of the Whole Bible
Proverbs 30:19
The way of an eagle in the air,.... And so of any other bird; but this is mentioned, because it flies swiftest, and soars highest: but the way in which it goes is not known, nor can it be seen with the eye; it cuts the air, and passes through it, but leaves no track behind it which may be pointed to, and it may be said, that is the way the eagle took and flew towards heaven out of sight;
the way of a serpent upon a rock; a smooth hard rock; and wonderful it is that it should creep up it without legs; and where it leaves no impression, no footsteps by which it can be traced, as it may in soft and sandy places;
the way of a ship in the midst of the sea; it is marvellous that such a vessel should be supported upon the sea; that it should weather the storms and tempests of it; that it should be steered through the trackless ocean to distant countries; and, particularly, though it makes furrows in the waters, and divides the waves; yet these quickly close again, and there is no path to be seen in which it goes; there is no beaten road made by it, nor by the vast numbers which go the same way, which a man can see with his eyes or follow;
and the way of a man with a maid; or "to a maid" x; the many artful ways and methods he uses to get into her company, who is kept recluse; and to convey the sentiments and affections of his heart unto her, to gain her love to him, and obtain her in an honourable way of marriage; or to decoy and deceive her, and draw her into impure and unlawful embraces: it may design the private and secret way of committing fornication with her; which sense seems to be confirmed by Proverbs 30:20. Some of the ancients, particularly Ambrose y, interpreted the whole of this verse of Christ: "the way of an eagle in the air", of his ascension to heaven, with men his prey, taken out of the jaws of the enemy; and which is such as is beyond the comprehension of men, that one of so great majesty should vouchsafe to come down from heaven, or ascend thither: "the way of a serpent upon a rock" he understands of the temptations of Satan, the old serpent, with which he attacked Christ, the Rock; but could imprint no footsteps of his malice and wickedness on him; could find nothing in him to work upon, nor leave any sign behind him, as upon Adam: "the way of a ship in the midst of the sea" he interprets of the church; which though distressed with storms and tempests of persecution and false doctrine, yet cannot suffer shipwreck, Christ being in it: and the last clause he renders as the Vulgate Latin version does, "and the way of a man in youth"; which he explains of the journeys which Christ took, and the ways of virtue he pursued, to do good to the bodies and souls of men, which are so many as not to be numbered. But it may be better interpreted of the wonderful incarnation of Christ, his conception and birth of a virgin; which was a new and unheard of thing, and the way and manner of it quite inscrutable, and more hard and difficult to be understood than any of the rest; for the words may be rendered, "the way of a man in a maid" or "virgin"; that is, the conception of Geber, the mighty man, in the virgin; see Jeremiah 31:22. Gussetius z gives the mystical sense of the whole, as referring to the ascension of Christ; his coming out of the stony grave; his conversation among the people, like the tumultuous waves; and his incarnation of a virgin.
