'Wolves' in the Bible

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

Their horses also are swifter than the leopards, and are more fierce than the evening wolves: and their horsemen shall spread themselves, and their horsemen shall come from far; they shall fly as the eagle that hasteth to eat.

Her princes within her are roaring lions; her judges are evening wolves; they gnaw not the bones till the morrow.
