18 There are three things which are too wonderful for me, Four which I do not understand : 19 The way of an eagle in the sky , The way of a serpent on a rock , The way of a ship in the middle of the sea , And the way of a man with a maid . 20 This is the way of an adulterous woman : She eats and wipes her mouth , And says , "I have done no wrong ."

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.
