Ezekiel 34:15-20

I myself will be the shepherd of my sheep, and I will cause them to lie down, saith the Lord Jehovah. I will seek that which was lost, and will bring back that which was driven away, and will bind up that which was broken, and will strengthen that which was sick: but the fat and the strong I will destroy; I will feed them in justice. And as for you, O my flock, thus saith the Lord Jehovah: Behold, I judge between sheep and sheep, the rams and the he-goats. Seemeth it a small thing unto you to have fed upon the good pasture, but ye must tread down with your feet the residue of your pasture? and to have drunk of the clear waters, but ye must foul the residue with your feet? And as for my sheep, they eat that which ye have trodden with your feet, and they drink that which ye have fouled with your feet. Therefore thus saith the Lord Jehovah unto them: Behold, I, even I, will judge between the fat sheep and the lean sheep.
