Proverbs 30:15-23

15The leech has two daughters: Give and Give.

There are three things that are never satisfied, four that never say, ‘Enough!’:

16Sheol, the barren womb, land never satisfied with water, and fire that never says, ‘Enough!’

18There are three things too wonderful for me, four that I cannot understand:

19the way of an eagle in the sky, the way of a snake on a rock, the way of a ship at sea, and the way of a man with a maiden.

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

22a servant who becomes king, a fool who is filled with food, 23an unloved woman who marries, and a maidservant who supplants her mistress.
