18 There are three things which are too wonderful for me, Yes, four which I do not understand: 19 The way of an eagle in the air, The way of a serpent on a rock, The way of a ship in the midst of the sea, And the way of a man with a virgin. 20 This is the way of an adulterous woman: She eats and wipes her mouth, And says, "I have done no wickedness."
Matthew Henry's Commentary on Proverbs 30:18-20
Commentary on Proverbs 30:18-20
(Read Proverbs 30:18-20)
Four things cannot be fully known. The kingdom of nature is full of marvels. The fourth is a mystery of iniquity; the cursed arts by which a vile seducer gains the affections of a female; and the arts which a vile woman uses to conceal her wickedness.
