λύκος

For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.

But 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.

Go your ways: behold, I send you forth as lambs among wolves.

Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.

Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves.
