### Core Meaning & Semantic Range
The Greek word **katabrabeúō**, represented by `{{G2603}}`, means to award a prize against someone, or to figuratively **defraud** them of salvation. It is translated as "beguile of reward." This specific term appears **3 times** within a single, unique verse in the Bible, highlighting its focused application as a warning.
### Biblical Occurrences & Contextual Analysis
The sole use of `{{G2603}}` is found in a direct warning to believers. In [[Colossians 2:18]], the text cautions, "Let no man **beguile** you of your reward." The passage describes the methods of this deception, which include a "voluntary humility" and the "worshipping of angels." This act of defrauding is characterized as being undertaken by someone who is "vainly puffed up by his fleshly mind," indicating that the deception is rooted in human pride and not divine truth.
### Related Words & Concepts
Several related words from its context in [[Colossians 2:18]] help clarify the nature of this warning:
* `{{G3367}}` **mēdeís** (no man): This specifies the source of the deception, warning believers to let "not even one" person lead them astray.
* `{{G5012}}` **tapeinophrosýnē** (humility): Defined as "humiliation of mind, i.e. modesty," it is presented here as a false or voluntary humility used as a tool for deception.
* `{{G2356}}` **thrēskeía** (worshipping): This word for "ceremonial observance" points to the practice of angel worship as a specific way believers were being defrauded of their reward.
* `{{G5448}}` **physióō** (puffed up): Meaning "to inflate, i.e. (figuratively) make proud," this describes the arrogant internal state of the person attempting to beguile others.
* `{{G4561}}` **sárx** (flesh): The source of the deception is a "fleshly mind," connecting it to "human nature (with its frailties... and passions)" rather than the Spirit.
### Theological Significance
The theological weight of `{{G2603}}` is concentrated in its function as a specific alert against spiritual fraud.
* **Defrauding of a Prize:** The term itself implies that a reward or prize is at stake, which the false teacher attempts to disqualify the believer from receiving.
* **Deceptive Asceticism:** The warning is directed at practices that appear spiritual, such as "voluntary humility" and "ceremonial observance," but are actually hollow and lead people away from the true prize [[Colossians 2:18]].
* **Pride-Based Doctrine:** The source of this beguiling doctrine is not God, but a mind "puffed up" `{{G5448}}` by the "flesh" `{{G4561}}`. It cautions that impressive-looking religious acts can be rooted in pride.
### Summary
In summary, `{{G2603}}` is not a general term for deception but a precise warning against being cheated out of a spiritual reward by false teachers. Its singular appearance in [[Colossians 2:18]] frames it as a caution against those who promote man-made religious observances, rooted in a prideful and "fleshly mind," as a substitute for true faith and the salvation that comes with it.
