Proverbs 30:15-23

15The leech has two daughters: Give and Give. Three things are never satisfied; four never say, "Enough":

16Sheol, the barren womb, the land never satisfied with water, and the fire that never says, "Enough."

17The eye that mocks a father and scorns to obey a mother will be picked out by the ravens of the valley and eaten by the vultures.

18Three things are too wonderful for me; four I do not understand:

19the way of an eagle in the sky, the way of a serpent on a rock, the way of a ship on the high seas, and the way of a man with a virgin.

20This is the way of an adulteress: she eats and wipes her mouth and says, "I have done no wrong."

21Under three things the earth trembles; under four it cannot bear up:

22a slave when he becomes king, and a fool when he is filled with food;

23an unloved woman when she gets a husband, and a maidservant when she displaces her mistress.
