Learn More →ἅρπαξ describes someone as “rapacious,” a term applied to predatory religious impostors and to socially destructive types listed alongside other vices. It appears in a warning about inward character (Matthew), in a Pharisee’s self-congratulatory prayer (Luke), and in Paul’s instructions about association and inheritance in the church (1 Corinthians).

Root and Related Words
ἅρπαξ is related to the verb harpazō (ἁρπάζω), “to seize” (Strong’s G726).

Occurrences
“Beware of false prophets, who come to you in sheep’s clothing, but inwardly are ravening wolves.” (Matthew 7:15)
Here the word is embedded in a vivid contrast between outward appearance and inward reality. The false prophets “come…in sheep’s clothing,” projecting harmlessness and belonging; yet the inside is pictured as “ravening wolves.” In that image, “rapacious” functions as a moral diagnosis expressed through animal behavior: a predator that feeds on others. The warning aims at discernment—what must be evaluated is not merely the presented identity (“sheep’s clothing”) but the inward appetite and intent that the wolf-image conveys. The term thus contributes a sense of dangerous aggressiveness concealed beneath religious guise.

The Pharisee stood and prayed to himself like this: ‘God, I thank you that I am not like the rest of men, extortionists, unrighteous, adulterers, or even like this tax collector.” (Luke 18:11)
In Luke, the word appears in a list the Pharisee uses to separate himself from “the rest of men.” Within the prayer’s rhetoric, “extortionists” stands as a representative example of what he considers obvious moral failure, placed with “unrighteous” and “adulterers,” and sharpened by the comparison “or even like this tax collector.” The rapacious person, in this setting, is a social type recognizable by grasping behavior toward others, a category the speaker cites to reinforce his own self-image. The word’s force comes from its role in boundary-making: it is the kind of person the Pharisee thanks God he is not, a foil used to elevate the speaker rather than to confess need.
yet not at all meaning with the sexual sinners of this world, or with the covetous and extortionists, or with idolaters; for then you would have to leave the world. (1 Corinthians 5:10)
Paul uses the term while clarifying what he did not mean by earlier instruction. The phrase “sexual sinners of this world” sets the sphere, and within that world he includes “the covetous and extortionists, or with idolaters.” “Extortionists” here is grouped with covetousness—desire that reaches outward to take—and with idolatry, suggesting a pattern of life that injures community life. Paul’s argument also places the word inside a practical claim: complete separation from such people in “the world” would require leaving the world entirely. The term therefore contributes to a realistic moral map: rapacious conduct is part of the world’s moral landscape, and believers will inevitably encounter it outside the church.
But as it is, I wrote to you not to associate with anyone who is called a brother who is a sexual sinner, or covetous, or an idolater, or a slanderer, or a drunkard, or an extortionist. Don’t even eat with such a person. (1 Corinthians 5:11)
This occurrence sharpens the focus from “this world” to “anyone who is called a brother.” The same kind of conduct now becomes a matter of church discipline and communal boundaries. “Extortionist” appears as the final item in a catalog that ranges from sexual sin and covetousness to idolatry, slander, and drunkenness; the list paints a picture of ongoing patterns, not momentary lapses, as markers of someone whose life contradicts the name “brother.” Paul’s directive, “Don’t even eat with such a person,” gives the term immediate social weight: rapacious behavior is not merely privately regrettable but is corrosive enough to restrict table fellowship. In this scene, the word helps define which behaviors rupture the ordinary signs of communion and shared life.
nor thieves, nor covetous, nor drunkards, nor slanderers, nor extortionists, will inherit God’s Kingdom. (1 Corinthians 6:10)
Here the term stands inside an eschatological warning: certain identities and behaviors are incompatible with inheriting “God’s Kingdom.” It is positioned near “thieves” and “covetous,” aligning rapacity with taking what belongs to others and with the desire that drives such taking, and it is also linked with “drunkards” and “slanderers,” which damage persons and community in different ways. The word functions not as a passing description but as a category of life that carries consequences. Within the compressed phrasing of the verse, “extortionists” names a type whose predatory grasping is treated as decisive for the stated outcome.
Sense and Usage
Across these passages, “rapacious” appears in two main frames: (1) predatory inward character masked by a pious exterior, and (2) a vice-category that damages communal life and must be named plainly. Matthew 7:15 presents rapacity as something internal (“inwardly”), emphasizing hidden motive and appetite; the wolf imagery makes the danger vivid by portraying predation rather than mere error. Luke 18:11 places rapacity within moral self-comparison, showing how the category can be invoked to distinguish “us” from “them,” and how easily it can serve self-justification. In 1 Corinthians, the term becomes part of pastoral instruction: Paul distinguishes unavoidable contact with rapacious people in “the world” (5:10) from the required refusal of recognized fellowship with one “called a brother” who persists in such conduct (5:11). Finally, 6:10 frames rapacity within a list that warns of exclusion from the kingdom, giving the term ultimate seriousness beyond social inconvenience.
The usage also shows that the word can function as a metaphor (wolves) or as a straightforward moral label (extortionists). In either case, the underlying picture remains consistent within the passages: a rapacious person is one whose stance toward others is grasping and predatory rather than protective and just. The proximity to “covetous” in multiple Corinthian lists highlights rapacity’s outward-pressing direction—desire that does not stay inward but expresses itself in harmful taking—while the pairing with “thieves” in 6:10 sets it among actions that deprive others. Even where the term sits in a list, it is not vague; it helps define the kind of social harm that the community must recognize, whether by discernment (Matthew), by the exposure of self-righteous speech (Luke), or by boundaries of association and accountability (1 Corinthians).
Imagery
Matthew’s “ravening wolves” supplies the dominant picture: rapacity as an inward hunger that threatens the flock while wearing a disguise. Paul’s lists translate that same predatory impulse into community terms—conduct that cannot be normalized at the table (1 Corinthians 5:11) and cannot be treated lightly when the kingdom is in view (1 Corinthians 6:10). Luke shows how the label can be spoken from a posture of self-trust (“I thank you that I am not…”), reminding readers that naming rapacity in others does not itself constitute righteousness.
