Proverbs 30:15-17

15“The leech has two daughters. ‘Give! Give!’ they cry. “There are three things that are never satisfied, four that never say, ‘Enough!’:

16the grave, the barren womb, land, which is never satisfied with water, and fire, which never says, ‘Enough!’

17“The eye that mocks a father, that scorns an aged mother, will be pecked out by the ravens of the valley, will be eaten by the vultures.
