### Core Meaning & Semantic Range
The Greek term σφυρόν (transliterated as *sphyrón*) denotes the "ankle" or "ankle bone." Its etymological root is believed to be connected to a word signifying "a ball" or "sphere," highlighting the globular shape of the ankle joint. This anatomical specificity suggests a literal and precise meaning, referring directly to a part of the human lower limb. Unlike many biblical terms that possess broad metaphorical or theological extensions, σφυρόν appears to maintain a singular, concrete semantic range, focusing solely on its physical reality. There is no evidence within its base definition or usage to suggest a figurative or symbolic application.
### Biblical Occurrences & Contextual Analysis
The word σφυρόν appears only once in the New Testament, in the book of Acts. This singular occurrence is found in the narrative of Peter's miraculous healing of the lame man at the Beautiful Gate: "And taking him by the right hand he raised him up, and immediately his feet and ankle bones were strengthened" [[Acts 3:7]]. The context is crucial for understanding the word's significance. The lame man had been unable to walk from birth, indicating a profound physical disability. The immediate and complete strengthening of his "feet and ankle bones" (τὰ σφυρὰ αὐτοῦ) underscores the miraculous nature of the healing. This was not a gradual recovery but an instantaneous restoration of a fundamental anatomical structure essential for mobility. The precision of the term emphasizes the tangible and undeniable reality of the divine intervention, demonstrating God's power to restore even the most basic physical functions.
### Related Words & Concepts
While σφυρόν itself is a unique occurrence, its meaning connects it to several broader biblical concepts and related anatomical terms. As a component of the human body, it naturally relates to words describing other body parts, particularly those associated with movement, such as "feet" (πούς) and "legs." Conceptually, its appearance in [[Acts 3:7]] links it directly to themes of physical infirmity, miraculous healing, and divine power. The strengthening of the ankle bones is a prerequisite for walking and standing, thereby connecting σφυρόν to concepts of mobility, stability, and the restoration of full human function. It stands in contrast to terms describing weakness, paralysis, or inability to move. The etymological link to "sphere" or "ball" points to the anatomical understanding of joints as rounded structures facilitating movement.
### Theological Significance
The singular use of σφυρόν in [[Acts 3:7]] carries profound theological weight. It serves as a concrete detail in a narrative that powerfully demonstrates the physical reality of God's redemptive work through His apostles. The immediate strengthening of the lame man's "ankle bones" highlights several theological truths:
1. **Divine Power over Physical Limitation:** God's power is not limited to spiritual transformation but extends to the complete restoration of the physical body, overcoming congenital defects.
2. **Tangible Manifestation of the Spirit:** The miracle, attested by the precise detail of the strengthened ankle bones, provides undeniable evidence of the Holy Spirit's active presence and power in the early church.
3. **Completeness of Healing:** The instantaneous and thorough nature of the healing, affecting even the foundational "ankle bones," signifies God's desire for holistic restoration. It was not a partial or temporary fix but a complete renewal enabling the man to walk, leap, and praise God.
4. **Basis for Witness:** This physical miracle, centered on the restored ankle bones, became a powerful testimony to the crowds in Jerusalem, leading to many believing in Jesus.
### Summary
The Greek word σφυρόν (*sphyrón*) refers specifically to the "ankle" or "ankle bone," deriving from a root associated with spherical shapes, aptly describing the joint. Its sole appearance in the New Testament, in [[Acts 3:7]], is pivotal. Here, it describes the instantaneous strengthening of the lame man's ankle bones by divine power, enabling him to walk for the first time. This precise anatomical detail underscores the tangible and complete nature of God's miraculous healing, demonstrating His sovereignty over physical infirmity and providing a powerful witness to the early church's divine mandate. The word, though rare, thus plays a crucial role in illustrating the physical reality and comprehensive scope of God's restorative power.
