Word Study

In depth

A plain-language study of pyretós — the range of meaning it carries, how Scripture actually uses it, and where it points. Written for readers who don’t know the original language.

Core Meaning & Semantic Range

The Greek word pyretós, represented by G4446, is the term for fever. It appears 6 times across 6 unique verses in the Bible. Derived from a word meaning "inflamed," it is used exclusively as a noun to describe a physical state of being feverish due to illness.

Biblical Occurrences & Contextual Analysis

In the biblical narrative, G4446 consistently appears in the context of sickness and subsequent healing. In the Gospels, it describes the condition of Simon's mother-in-law, who was taken with a "great fever" Luke 4:38. Jesus's power over the ailment is shown when He "rebuked the fever" Luke 4:39 or simply "touched her hand, and the fever left her" Matthew 8:15. A similar account notes that after His touch, "immediately the fever left her" Mark 1:31. The term is also used to describe the condition of an official's son John 4:52 and the father of Publius, who was sick with a fever and a bloody flux Acts 28:8.

Related Words & Concepts

Several related words provide context for the sickness and healing associated with fever:

  • G1420 dysentería (a "dysentery":--bloody flux): This term is used alongside fever to describe the compound illness afflicting the father of Publius, highlighting the severity of his condition Acts 28:8.
  • G2390 iáomai (to cure (literally or figuratively):--heal, make whole): This verb describes the action taken against the fever. After Paul prayed, he healed Publius's father of his sickness Acts 28:8.
  • G2866 kompsóteron (figuratively, convalescent:--+ began to amend): This word signifies the beginning of recovery from illness. An official asked at what hour his son, who had a fever, "began to amend" John 4:52.

Theological Significance

The use of G4446 carries significance by demonstrating divine authority over physical infirmity.

  • Power over Sickness: The healing of a fever is shown to be subject to supernatural power. Jesus is depicted as having direct command over the illness, "rebuking" it as one would a person or spirit Luke 4:39.
  • Immediate Restoration: The healings are characteristically immediate. Upon Jesus's intervention, the fever leaves "immediately" Mark 1:31, and the healed person is restored to the point of being able to serve others Luke 4:39.
  • Confirmation of Authority: The departure of the fever serves as a sign. In the healing of the official's son, the fact that the fever left at the exact hour Jesus spoke confirms his authority even from a distance John 4:52.

Summary

In summary, G4446 is a specific medical term whose primary role in Scripture is to set the stage for a demonstration of divine power. While it literally means fever, its presence in the text serves to highlight the authority of Jesus and his apostles to heal, often instantly and completely. The word is not merely descriptive of an illness but is instrumental in narratives that validate spiritual power over the physical realm.
