'Slaughter' in the Bible

Thus says Yahweh my God: "Feed the flock of slaughter.

Their buyers slaughter them, and go unpunished. Those who sell them say, 'Blessed be Yahweh, for I am rich;' and their own shepherds don't pity them.

So I fed the flock of slaughter, especially the oppressed of the flock. I took for myself two staffs. The one I called "Favor," and the other I called "Union," and I fed the flock.
