Ezekiel 34:20-22

20“ ‘Therefore this is what the Sovereign LORD says to them: See, I myself will judge between the fat sheep and the lean sheep. 21Because you shove with flank and shoulder, butting all the weak sheep with your horns until you have driven them away, 22I will save my flock, and they will no longer be plundered. I will judge between one sheep and another.
