to defraud: to keep back or take away from someone what is rightfully owed to them
At its heart this word is not about theft but about refusal: holding back, or taking away, something that already belongs to another person by right. Its natural home is the world of money, wages, debts, and deposits, where one party owes another and simply fails to hand over what is due. That is why English versions reach for words like "defraud," "deprive," and "withhold" depending on the verse.
It helps to set this word apart from its neighbors. It is not stealing in secret (κλέπτω) or snatching by force (ἁρπάζω); the wrong is failing to give back or hand over what someone is owed. In one place Paul sets it right beside the broad word for doing injustice (ἀδικέω), as the sharper, money-specific form of that larger wrong.
The New Testament stretches this one idea across three settings:
- literal fraud, such as cheating a fellow believer in a property dispute or holding back a laborer's earned wages
- a husband or wife depriving the other of the intimacy each is owed within marriage
- people who have been robbed of the truth itself by false teaching
In every case the core holds steady: someone is being kept from what is genuinely theirs.
