Ezekiel 34:22-24

therefore will I save my flock, and they shall no more be a prey; and I will judge between sheep and sheep. And I will set up one shepherd over them, and he shall feed them, even my servant David; he shall feed them, and he shall be their shepherd. And I, Jehovah, will be their God, and my servant David prince among them; I, Jehovah, have spoken it.
