κλέπτης

a thief

Definition

A κλέπτης is a thief, someone who steals by stealth or deception. In the New Testament, it primarily refers to a literal thief who breaks in to steal material possessions (Matthew 6:19-20, Luke 12:33). However, it is also used metaphorically by Jesus to describe false religious leaders who enter the spiritual 'sheepfold' not by the true door (Christ himself) but by another way, aiming to steal, kill, and destroy (John 10:1, 10:10). This metaphorical use contrasts the thief's destructive intent with Jesus' life-giving purpose.

Biblical Usage

The word is used 16 times, appearing in the Gospels and Epistles. In the Synoptic Gospels (Matthew, Luke), it often appears in Jesus' teachings about earthly treasures and the unexpected coming of the Son of Man, likened to a thief in the night (Matthew 24:43, Luke 12:39). In John's Gospel, it is used exclusively in the Good Shepherd discourse (John 10) as a potent metaphor for false messiahs and corrupt leaders. The epistles (1 Corinthians 6:10, 1 Peter 4:15) list thieves among those who will not inherit the kingdom of God, emphasizing the ethical seriousness of the act.

Etymology

Derived from the verb κλέπτω (kleptō, G2813), meaning 'to steal' or 'to act secretly.' The root implies stealth and deception, not open robbery. This gives the noun its core sense of one who takes by covert means. English words like 'kleptomania' derive from this same Greek root.

Semantic Range

This word is theologically significant as Jesus uses it to define his own mission by contrast. In John 10:10, the thief comes to 'steal and kill and destroy,' but Jesus comes to give 'life abundantly.' This frames spiritual conflict: false teachers and the devil himself (cf. John 8:44) are characterized as thieves who plunder souls, while Christ is the true shepherd and giver of life. Understanding this metaphor enriches the reading of passages about false prophets and the security found in Christ alone.

In the ancient Greco-Roman world, thieves (κλέπται) were a common threat, often breaking through the mud-brick walls of homes (Matthew 6:19-20, 24:43). Unlike a robber (λῃστής, lēstēs, G3027) who might use open violence, a κλέπτης was associated with stealth and deception, making the metaphor for false teachers particularly apt. The cultural fear of a nighttime thief made it a powerful image for the unexpected coming of divine judgment.

λῃστής (lēstēs, G3027) — a robber or bandit, often using violence or operating in gangs (e.g., the parable of the Good Samaritan). ἅρπαξ (harpax, G727) — a swindler, extortioner, or rapacious person, emphasizing greedy seizure.
