Proverbs 30:19

the way ¹  of an eagle in the sky, the way of a snake on a rock, the way of a ship in the sea, and the way of a man with a woman. ² 

Ex 22:16; Job 39:27; Isa 40:31

¹ sn It is difficult to know for certain what these four things had in common for the sage. They are all linked by the word “way” (meaning “a course of action”) and by a sense of mystery in each area. Suggestions for the connections between the four include: (1) all four things are hidden from continued observation, for they are in majestic form and then gone; (2) they all have a mysterious means of propulsion or motivation; (3) they all describe the movement of one thing within the sphere or domain of another; or (4) the first three serve as illustrations of the fourth and greatest wonder, which concerns human relationships and is slightly different than the first three.

² tn This last item in the series is the most difficult to understand. The MT reads וְדֶּרֶךְ גֶּבֶר בְּעַלְמָה (vÿderekh gever bÿ’almah, “and the way of a man with a maid,” so KJV, NASB). The last term does not in and of itself mean “virgin” but rather describes a young woman who is sexually ready for marriage. What is probably in view here is the wonder of human sexuality, for the preposition בְּ (bet) in this sequence indicates that the “way of the man” is “with” the woman. This mystery might begin with the manner of obtaining the love of the young woman, but focuses on the most intimate part of human relationships. And all of this was amazing to the sage. All of it is part of God’s creative plan and therefore can be enjoyed and appreciated without fully comprehending it.
