Deceit (1):
de-set' (mirmah; (dolos)): The intentional misleading or beguiling of another; in Scripture represented as a companion of many other forms of wickedness, as cursing (Psalms 10:7), hatred (Proverbs 26:24), theft, covetousness, adultery, murder (Mark 7:22, Romans 1:29). The Revised Version (British and American) introduces the word in Proverbs 14:25, 2 Thessalonians 2:10; but in such passages as Psalms 55:11, Proverbs 20:17, Proverbs 26:26, 1 Thessalonians 2:3, renders a variety of words, more accurately than the King James Version, by "oppression," "falsehood," "guile," "error."
