λύκος

a wolf, jackal

Definition

The Greek word λύκος refers primarily to a wolf, a predatory animal known for its danger to flocks. In the New Testament, it is used both literally and metaphorically. Literally, it describes the animal that threatens sheep, as seen in John 10:12 where the hired hand abandons the sheep to the wolf. Metaphorically, it symbolizes false teachers or malicious individuals who pose a spiritual threat to God's people, such as the 'false prophets' who come in sheep's clothing in Matthew 7:15 and the 'fierce wolves' who will attack the church in Acts 20:29.

Biblical Usage

In the New Testament, λύκος appears five times, always in a negative, threatening context. It is used in Jesus' teachings to warn of spiritual danger: in Matthew 7:15 and 10:16, and Luke 10:3, it metaphorically represents deceptive or hostile opponents. In John 10:12, it illustrates a literal physical threat to the flock, underscoring the shepherd's duty. Finally, in Acts 20:29, Paul uses it prophetically to describe future false teachers who will ravage the church.

Etymology

The word λύκος is the standard ancient Greek term for 'wolf,' derived from the Proto-Indo-European root *wĺ̥kʷos. It is a primary noun with no complex derivation within Greek itself. Cognates appear in many languages, such as Latin 'lupus,' Sanskrit 'vṛkaḥ,' and English 'wolf.' Its meaning remained stable, consistently denoting the predatory canine.

Semantic Range

Λύκος is theologically significant as a vivid metaphor for spiritual deception and persecution. It reinforces the biblical theme of the church as a vulnerable flock needing protection from Christ, the true shepherd (John 10). Understanding this metaphor enriches reading by highlighting the seriousness of false teaching (Matthew 7:15, Acts 20:29) and the call for believers to be both 'innocent as doves and shrewd as serpents' (Matthew 10:16) in a hostile world.

In the ancient Near Eastern and Greco-Roman world, wolves were universally feared as ruthless predators of livestock, often operating in packs. This made them a powerful and immediate symbol of destruction, treachery, and greed. The metaphorical use would resonate strongly with an agrarian society familiar with the constant threat wolves posed to their economic livelihood and community safety.

θὴρ (thēr, G2342) — a more general term for a wild beast or predator. | ἁρπαγή (harpagē, G724) — emphasizes the act of seizing or snatching away, which is the wolf's action.
