Proverbs 30:15-17

The leech has two daughters— Give and Give! There are three things that are never satisfied, Four never say, “Enough!”: The grave, The barren womb, The earth that is not satisfied with water— And the fire never says, “Enough!” The eye that mocks his father, And scorns obedience to his mother, The ravens of the valley will pick it out, And the young eagles will eat it.
