λεπρός

a leper

Definition

In the New Testament, λεπρός refers to a person afflicted with leprosy, a term that encompassed various severe skin diseases in the ancient world, not just Hansen's disease (modern leprosy). These conditions rendered a person ritually unclean under Mosaic Law (Leviticus 13–14), requiring isolation from the community. The word is used exclusively for the afflicted individuals themselves, such as the leper who approaches Jesus for healing in Matthew 8:2 and the lepers mentioned in Jesus's instructions to the disciples in Matthew 10:8. In passages like Matthew 11:5 and Luke 7:22, 'lepers are cleansed' is cited as a messianic sign, demonstrating Jesus's power to restore both physical health and social standing.

Biblical Usage

The word is used 9 times, exclusively in the Gospels (Matthew, Mark, Luke). It appears in narratives of healing (Matthew 8:2, Mark 1:40), in summaries of Jesus's miraculous ministry as proof of his messianic identity (Matthew 11:5, Luke 7:22), and in his instructions to disciples (Matthew 10:8). It also appears in the story of the anointing at Bethany, where Simon is identified as a former 'leper' (Matthew 26:6, Mark 14:3), indicating someone who had been cleansed. The usage consistently highlights leprosy as a symbol of profound impurity and social ostracism overcome by Jesus's compassion and power.

Etymology

Derived from the Greek λέπρα (lepra), meaning 'scale' or 'scab,' referring to the scaly appearance of the skin disease. The adjective λεπρός literally means 'scaly' or 'affected with leprosy.' It is related to the verb λέπω (lepō), 'to peel.' In the Septuagint (the Greek Old Testament), it translates the Hebrew צָרַעַת (tsara'ath), which covered a range of skin diseases and mold in fabrics or houses.

Semantic Range

The term is theologically significant as leprosy served as a powerful metaphor for sin and ritual impurity in Jewish thought. Jesus's healing of lepers demonstrated his authority over the Mosaic Law's purity codes and his mission to restore outcasts, fulfilling Old Testament prophecies (e.g., Isaiah 53:4). Each cleansing was a tangible sign of the inbreaking Kingdom of God, where physical and spiritual restoration occur. Understanding this context enriches reading by showing that these healings were about holistic salvation—reintegrating the marginalized into the community of God's people.

In first-century Jewish culture, a λεπρός was not only physically ill but also ceremonially unclean (Leviticus 13:45-46). They were required to live apart, warn others of their presence, and wear torn clothes. Healing required priestly verification and a sacrifice (Leviticus 14). Thus, a leper was a profound social and religious outcast. The modern clinical understanding of Hansen's disease is narrower; the biblical term likely included various contagious skin conditions like psoriasis or vitiligo that carried the same severe social and religious consequences.

λέπρα (lepra, G3014) — The disease itself (leprosy), not the person afflicted. ἀκάθαρτος (akathartos, G169) — A broader term for 'unclean' or 'impure,' which could describe a leper's ritual state, but applies to many forms of impurity.
