deceit: the deliberate trick or false appeal by which someone is misled into believing or wanting what is not real
This word names the active deception itself, the trick, stratagem, or false promise, not the mistaken state it leaves a person in (πλάνη). Across the New Testament it is almost always rendered "deceit" or "deceitfulness", and the word behaves as a near power in its own right: people are ruled by desires that come from Deceit, or taken in by an empty deceit dressed up as wisdom.
What gives the word its edge in these texts is that the deception works by luring. Wealth, sin, false teaching, and the great adversary all mislead by holding out something attractive that they cannot actually deliver:
- The deceitfulness of riches promises security
- sin promises satisfaction
- the false teacher promises depth
In each case the trap is baited, so the word sits very close to seduction even while it means "deceit".
One passage pulls in a different direction. In 2 Peter 2:13, written amid a scene of feasting and luxury, many scholars hear the word as "pleasures" or "dissipations" rather than "deceptions", possibly as a pointed play on the love-feasts named in Jude. Whether that is a genuine second sense or only the color the setting lends the ordinary meaning is disputed, and it affects no other verse.
Nuances
Whether ἀπάταις in 2 Peter 2:13 means deceptions or pleasures, dissipations, possibly a deliberate play on the love-feasts (ἀγάπαις) of Jude 12.
