18 “There are three things which are too amazing for me,
four which I don’t 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 maiden. 20 “So is the way of an adulterous woman:
she eats and wipes her mouth,
and says, ‘I have done nothing 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.
