Proverbs 30:15-17

The leech has two suckers that cry out, “More, more!” There are three things that are never satisfied— no, four that never say, “Enough!”: the grave, the barren womb, the thirsty desert, the blazing fire. The eye that mocks a father and despises a mother’s instructions will be plucked out by ravens of the valley and eaten by vultures.
