Napkin Please?

Proverbs 30:18-20 (NASB)

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.”
