### Core Meaning & Semantic Range
The Greek word **diakatharízō**, represented by `{{G1245}}`, means to **cleanse perfectly** or to **winnow**. It is derived from διά and καθαρίζω. This specific term appears only **2 times** across **2 unique verses** in the Bible, highlighting its focused and powerful meaning in the context of purification and separation.
### Biblical Occurrences & Contextual Analysis
In its biblical usage, `{{G1245}}` is found in two parallel accounts describing a powerful metaphor for judgment. In both Matthew and Luke, the word illustrates an act of decisive separation, where a fan is used to **thoroughly purge** a threshing floor. This action divides the valuable wheat, which is gathered into a garner, from the worthless chaff, which is destined for destruction by fire ([[Matthew 3:12]]; [[Luke 3:17]]). The context is explicitly agricultural, using the process of winnowing to symbolize a divine sorting.
### Related Words & Concepts
Several related words help clarify the imagery associated with this act of perfect cleansing:
* `{{G4425}}` **ptýon** (a winnowing-fork (as scattering like spittle):--fan): This is the tool used to perform the action of purging the floor, as mentioned in both [[Matthew 3:12]] and [[Luke 3:17]].
* `{{G4863}}` **synágō** (to lead together, i.e. collect or convene): This word describes the positive outcome of the purging process, where the wheat is gathered. It is also used more broadly for the gathering of all nations for judgment [[Matthew 25:32]].
* `{{G2618}}` **katakaíō** (to burn down (to the ground), i.e. consume wholly): This describes the fate of the chaff after it has been separated. The term signifies complete consumption by fire, as seen in the judgment of Babylon, which "shall be utterly burned with fire" [[Revelation 18:8]].
### Theological Significance
The theological weight of `{{G1245}}` is centered on the theme of final judgment and purification.
* **Perfect Separation:** The core meaning, "to cleanse perfectly," implies a process that leaves no room for mixture or error. It is an absolute and final sorting of the valuable from the worthless, as seen in the separation of wheat from chaff [[Matthew 3:12]].
* **Divine Judgment:** The act of purging is directly linked to inescapable consequences. While the wheat is gathered, the chaff is destroyed with "unquenchable fire" [[Luke 3:17]]. This connects the cleansing to a definitive and eternal judgment.
* **Contrasting Fates:** The use of `{{G1245}}` alongside `{{G4863}}` (gather) and `{{G2618}}` (burn up) establishes a stark contrast between two possible destinies: preservation and total destruction. This highlights the ultimate outcome of divine evaluation.
### Summary
In summary, `{{G1245}}` is a highly specific term that conveys an image of complete and perfect separation. Though used only twice, its context within the metaphor of winnowing makes it a powerful word for divine judgment. It illustrates a final, decisive action that purges the undesirable and gathers the valuable, defining the ultimate consequences of being found as either wheat or chaff.
