Deceit – To ensnare, take in, beguile, or cheat through trickery, treachery, lying, or concealment or distortion of the truth for the purpose of misleading.
God used this word in its various forms 155 times in Scripture: 98 times to Israel in their Masoretic Text Old Testament; 15 times to Israel in their Koine Greek Old Testament; 26 times to the Body of Christ in the Gospel of Grace (Romans-Philemon); and 16 times to Israel in their tribulation books (Hebrews-Revelation).
The greatest deceit is committed by religion, specifically Christianity.
