Ezekiel 34:22

20“Therefore the Lord GOD says to them: ‘Behold, I, even I, will judge between the fat sheep and the lean sheep.

21Because you thrust with side and with shoulder, and push all the diseased with your horns, until you have scattered them abroad,

22therefore I will save my flock, and they will no more be a prey. I will judge between sheep and sheep.

23I will set up one shepherd over them, and he will feed them, even my servant David. He will feed them, and he will be their shepherd.

24I, the LORD, will be their God, and my servant David prince among them. I, the LORD, have spoken it.
