The Greek word harpax functions as both an adjective ('ravenous,' 'rapacious') and a noun ('robber,' 'swindler'). It describes one who grabs greedily, seizes what belongs to others, or a predatory animal that tears its prey. The word carries connotations of both violent force and fraudulent extortion.
Jesus uses harpax to describe false prophets: 'they come to you in sheep's clothing, but inwardly they are ferocious wolves' (Matthew 7:15). The ravenous wolf disguised as a sheep is the perfect image of spiritual predation — using the language and appearance of godliness to exploit those under their influence. Paul uses the word in 1 Corinthians 6:10 to list swindlers among those who will not inherit the kingdom of God. The transformed believer is freed from this grasping spirit through the gospel, learning instead the generosity of Christ who gave all and grasped nothing for Himself.
