Boyd’s Bible Dictionary:

Wolves of Palestine were numerous and the dread of shepherds, as they were a terrible enemy to sheep

Concise Bible Dictionary:

Arabian Wolf in Jordan
The well-known animal, described in scripture as “ravening,” and seeking its prey in the evening. They are very destructive among the sheep, worrying and destroying more than they can eat. This makes the wolf a fit emblem of the wicked, who molest the sheep and lambs of God’s flock, and even creep in among them. How great will be the change in the millennium is denoted, among other things, by the wolf and the lamb dwelling together (Gen. 49:2727Benjamin shall ravin as a wolf: in the morning he shall devour the prey, and at night he shall divide the spoil. (Genesis 49:27); Isa. 11:66The wolf also shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together; and a little child shall lead them. (Isaiah 11:6); Isa. 65:2525The wolf and the lamb shall feed together, and the lion shall eat straw like the bullock: and dust shall be the serpent's meat. They shall not hurt nor destroy in all my holy mountain, saith the Lord. (Isaiah 65:25); Jer. 5:66Wherefore a lion out of the forest shall slay them, and a wolf of the evenings shall spoil them, a leopard shall watch over their cities: every one that goeth out thence shall be torn in pieces: because their transgressions are many, and their backslidings are increased. (Jeremiah 5:6); Ezek. 22:2727Her princes in the midst thereof are like wolves ravening the prey, to shed blood, and to destroy souls, to get dishonest gain. (Ezekiel 22:27); Hab. 1:88Their 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. (Habakkuk 1:8); Zeph. 3:33Her princes within her are roaring lions; her judges are evening wolves; they gnaw not the bones till the morrow. (Zephaniah 3:3); Matt. 7:1515Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves. (Matthew 7:15); Matt. 10:1616Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves. (Matthew 10:16); Luke 10:33Go your ways: behold, I send you forth as lambs among wolves. (Luke 10:3); John 10:1212But he that is an hireling, and not the shepherd, whose own the sheep are not, seeth the wolf coming, and leaveth the sheep, and fleeth: and the wolf catcheth them, and scattereth the sheep. (John 10:12); Acts 20:2929For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock. (Acts 20:29)). The Hebrew is zeeb, Arabic dhib, the common Canis lupus.
