Core Meaning & Semantic Range

The Greek word syntēréō, represented by G4933, is derived from σύν and τηρέω, meaning to keep closely together. It appears 4 times across 4 unique verses in the Bible. Its definition encompasses the ideas of conserving something from ruin, as well as mentally remembering or obeying.

Biblical Occurrences & Contextual Analysis

In its biblical usage, G4933 carries both a literal and a mental meaning. It is used twice in the parable of the new wine, where putting new wine G3631 into new bottles G779 ensures that both G297 are preserved (Matthew 9:17, Luke 5:38). This illustrates the physical act of conservation. The mental application is seen when Mary kept all these things and pondered them in her heart Luke 2:19, indicating a deep, internal remembrance. It is also used to describe how Herod observed John the Baptist, whom he knew to be a just G1342 and holy G40 man, suggesting a protective watchfulness Mark 6:20.

Related Words & Concepts

Several related words help clarify the contexts in which G4933 is used:

  • G3820 palaiós (old): This word, meaning antique or worn out, is used for the old bottles that cannot contain new wine Matthew 9:17. It provides a direct contrast to the new things that must be preserved.
  • G2588 kardía (heart): Defined as the thoughts or feelings, this is where Mary kept G4933 the events surrounding Jesus's birth Luke 2:19. This connects the act of preserving with the inner person, a place of deep reflection.
  • G5399 phobéō (to fear, revere): Herod feared John, which led him to observe or keep G4933 him Mark 6:20. This links the act of preservation to a sense of awe and reverence for righteousness.

Theological Significance

The theological weight of G4933 is seen in its various applications, highlighting how God's work is to be kept.

  • Preserving the New Covenant: The parable of new wine being preserved in new wineskins points to a foundational principle. The new work of God in Christ cannot be contained by old structures but must be placed in a new context to be conserved (Matthew 9:17, Luke 5:38).
  • Internalizing Divine Truth: Mary's example of keeping G4933 and pondering G4820 these things in her heart G2588 establishes a model for believers. It is not enough to witness God's actions; they must be treasured and remembered internally Luke 2:19.
  • Observing Righteousness: Herod's action of observing G4933 John the Baptist, a just G1342 and holy G40 man, illustrates a form of preservation driven by respect and fear. It shows that even those outside of full obedience can recognize and feel compelled to protect what is holy Mark 6:20.

Summary

In summary, G4933 moves beyond a simple definition of keeping something safe. It conveys a rich, dual meaning of both physical conservation and mental retention. Whether describing the preservation of new wine in new bottles, the reverent observation of a holy man, or the treasuring of divine events within one's heart, syntēréō emphasizes the vital importance of carefully and closely holding on to what is valuable and new.
