A — 1: ἀπάτη
(Strong's #539 — Noun Feminine — apate — ap-at'-ay )

"deceit or deceitfulness" (akin to apatao, "to cheat, deceive, beguile"), that which gives a false impression, whether by appearance, statement or influence, is said of riches, Matthew 13:22; Mark 4:19; of sin, Hebrews 3:13 . The phrase in Ephesians 4:22 , "deceitful lusts," AV, "lusts of deceit," RV, signifies lusts excited by "deceit," of which "deceit" is the source of strength, not lusts "deceitful" in themselves. In 2—Thessalonians 2:10 , "all deceit of unrighteousness," RV, signifies all manner of unscrupulous words and deeds designed to "deceive" (see Revelation 13:13-15 ). In Colossians 2:8 , "vain deceit" suggests that "deceit" is void of anything profitable.
