'Wolves' in the Bible

Her princes in the midst of her are like wolves ravening the prey, to shed blood, to destroy souls, to get dishonest gain.

And their horses are swifter than the leopards, and are more agile than the evening wolves; and their horsemen prance proudly, and their horsemen come from afar: they fly as an eagle that hasteth to devour.

Her princes in the midst of her are roaring lions; her judges are evening wolves, that leave nothing for the morning.
