Proverbs 30:18-20 NIV

18 "There are three things that are too amazing for me, four that I do not understand:
19 the way of an eagle in the sky, the way of a snake on a rock, the way of a ship on the high seas, and the way of a man with a maiden.
20 "This is the way of an adulteress: She eats and wipes her mouth and says, 'I've done nothing wrong.'1
