### Biblical Occurrences & Contextual Analysis
In its biblical usage, `{{G892}}` is part of a powerful agricultural metaphor for divine judgment. In both [[Matthew 3:12]] and [[Luke 3:17]], John the Baptist describes a coming figure who will use a **fan** `{{G4425}}` to "throughly purge" `{{G1245}}` his threshing **floor** `{{G257}}`. This process separates the valuable **wheat** `{{G4621}}`, which is gathered into a **garner** `{{G596}}`, from the worthless **chaff** `{{G892}}`, which is destined to be burned with unquenchable **fire** `{{G4442}}`.
### Related Words & Concepts
Several related words illuminate the context of separation and judgment associated with **chaff**:
* `{{G4621}}` **sîtos** (grain, especially wheat): This is the direct counterpart to chaff, representing what is valuable and preserved. While the chaff is destroyed, the **wheat** is gathered into a barn [[Matthew 3:12]].
* `{{G4425}}` **ptýon** (fan): This is the instrument of separation, defined as a "winnowing-fork." Its use initiates the process that divides the wheat from the chaff [[Luke 3:17]].
* `{{G2618}}` **katakaíō** (burn up, utterly): This verb, meaning to "consume wholly," describes the final fate of the chaff, highlighting the irreversible nature of its destruction [[Matthew 3:12]].
* `{{G4863}}` **synágō** (gather): This term describes the preservation of the wheat, standing in stark contrast to the destruction of the chaff. The wheat is collected, or gathered together, for safekeeping [[Luke 3:17]].
### Theological Significance
The theological weight of `{{G892}}` is centered on the theme of final judgment.
* **Symbol of Worthlessness:** **Chaff** is depicted as the useless byproduct of the harvest, separated from the valuable **wheat** `{{G4621}}` and discarded.
* **Inevitable Separation:** The imagery of the threshing **floor** `{{G257}}` being thoroughly purged `{{G1245}}` signifies a decisive and complete separation between two distinct groups.
* **Destined for Destruction:** The fate of the **chaff** is to be utterly consumed by **fire** `{{G4442}}`. The use of the verb **katakaíō** `{{G2618}}` emphasizes a total and final judgment from which there is no recovery [[Matthew 3:12]].
### Summary
In summary, **áchyron** `{{G892}}` is far more than a simple agricultural term. It serves as a potent and concise symbol for that which is worthless and destined for divine judgment. Its meaning is defined entirely by its contrast with wheat `{{G4621}}`, which is gathered and preserved. Though appearing rarely, the word provides a stark and unforgettable image of eschatological separation.
