18 Three things are too wonderful for me; four 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 girl.
20 This is the way of an adulteress: she eats, and wipes her mouth, and says, "I have done no wrong."

22 a slave when he becomes king, and a fool when glutted with food;
23 an unloved woman when she gets a husband, and a maid when she succeeds her mistress.
